Control Theory :-

Control theory is a field of applied mathematics which is relevant to the control of dynamical systems in various physical processes, systems and machines. The objective is to develop a model or algorithm governing the application of system inputs to drive the system to a desired state, ensuring a level of control stability; often with the aim to achieve a degree of optimality. Control theory has deep connections with classical areas of mathematics, such as the calculus of variations and the theory of differential equations.

Approximation Theory :-

Approximation Theory is an application and a sister branch of Functional Analysis. It addresses the question, Can we approximate a complexly structured function with a simpler known one? The answer is affirmative (with some restrictions!), and it is in the form of the Weierstrass approximation theorem. The German mathematician Karl Weierstrass stated and proved: Any continuous function on a compact support can be approximated with a polynomial of some suitable degree (you found the restrictions? Yes, continuity and compact domain are the requirements!). With this beautiful result, a new door opens in the area of mathematical analysis what we today know as Approximation Theory. To learn more about the history, people in approximation theory, and earlier contributions, we highly recommend visiting the webpage History of Approximation Theory Some recent applications of approximation theory can be found in modeling of road traffic noise, image processing, neural network, and fuzzy mathematics.

Orbital Mechanics :-

Orbital mechanics (also called astrodynamics) is the study of the motions of artificial satellites and space vehicles moving under the influence of forces such as gravity, atmospheric drag, thrust, etc. Orbital mechanics is a modern offshoot of celestial mechanics which is the study of the motions of natural celestial bodies such as the moon and planets. It is the application of the laws of physics to describing the motion of spacecraft and is needed to determine spacecraft trajectories and manoeuvres.

Fluid Dynamics :-

Research in fluid mechanics spans the spectrum of applied mathematics, and graduate students in this field develop skills in a broad range of areas, including mathematical modelling, analysis, computational mathematics, as well as physical intuition. These skills are interconnected, and hence form a marketable whole for the individuals, because the development of appropriate numerical methods and the set-up and interpretation of numerical simulations hinges on the use of theoretical models of varying complexity, as well as judicious application of the scientific method. Within the field of fluid dynamics there are many exciting problems, from theoretical problems such as the Clay Institute Millennium Prize for proving existence, uniqueness and regularity for the Navier-Stokes equations to applications in the areas of atmosphere, ocean and climate dynamics, astrophysical problems such as stellar wind dynamics, and the dynamics of shock waves. Research projects range from the development of simple models used to understand aspects of complicated physical processes, to the use of advanced theoretical and numerical methods.

Numerical Analysis:-

The area of numerical analysis is also known as numerical computation, numerical methods, numerical mathematics, computational mathematics, scientific computing or mathematical software, depending on which aspect of this broad subject is being emphasized. One can argue that the reason computers were invented was to perform numerical computations, and scientific computing continues to be one of the main driving forces in the development of advanced computing architectures. Several of the “Grand Challenges” in science are closely associated with numerical problems. The broad long-term goal of numerical analysts is to develop good software for the solution of problems of a mathematical nature that arise in science, engineering and business. Some faculties focus on standard problems to cover a wide range of activities in numerical computing, with particular emphasis on the development, analysis, testing and evaluation of numerical algorithms and the construction of efficient, robust and reliable mathematical software.

Theory of Relativity and Cosmology:-

Research interests include cosmological tests of general relativity; constraints on the cosmological parameters using observational data; nature of dark energy and the accelerating Universe; the physics of inflation and the evolution of matter perturbations; statistical and geometrical measures for quantifying large-scale structures. The faculties devote particular focus to the reconstruction technique, which allows the realization of any desired expansionary history of the universe by an accurate choice of potential or other functions defined within the theory. Our review provides a self-contained summary of recent findings, progress, open questions, and outlooks on future research directions.

Integral Transforms:-

Integral transforms are valuable for the simplification that they bring about, most often in dealing with differential equations subject to particular boundary conditions. Proper choice of the class of transformation usually makes it possible to convert not only the derivatives in an intractable differential equation but also the boundary values into terms of an algebraic equation that can be easily solved.

Graph Theory:-

In mathematics, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. In early nineteenth century graph theory was used to solve puzzles. But now graph theory is applicable in all domains like combinatorics, Chemistry, Economics, Finance and all engineering branches. Colouring, Domination and labelling are some parameter based branches of graph theory. Structural graph theory, Algebraic graph theory, Chemical graph theory, Extremal graph theory and Random graphs are some of the other branches in graph theory.

Fractal Interpolation:-

Fractals are irregular, no-where smooth, complex and unpredictable shapes and structures such as climate prediction modals, cancerous tumours, financial and economical series, bio electrical recordings, etc . As the name suggests, fractal interpolation techniques are keys to modal such intrinsic structures, without having to ignore the significant yet minute details they possess. The classical interpolation methods are nonrecursive functions that are non-differentiable at finite number of data points. If data points are generated from more irregular or complex functions, then the classical interpolants are not good approximations for such data. Fractal Interpolation Functions (FIF) defined via suitable Iterated Function Systems (IFS) possess the novelty of providing one of the very few methods that produce non-differentiable interpolants.

Optimization Theory:-

Optimization is the backbone of every system that involves decision making and optimal strategies. It plays an important role and influences our life directly or indirectly which cannot be avoided or neglected. Optimization is a key concept not only in mathematics, computer science, and operations research, and but also it is essential to the modeling of any system, playing an integral role in the computer-aided design. In recent years, optimization techniques become a considerable part of each system and applicable in a wide spectrum of industries, viz., aerospace, chemical, electrical, electronics, mining, mechanical, information technology, finance, and e-commerce sectors. Therefore, the very need is to easy understanding of the problem and implementation of optimization techniques with advanced computer-added design activity.

Fuzzy Computation:-

Fuzzy set theory was introduced by the late Lotfi Aliasker Zadeh in 1975. Since then, this theory has grabbed the excessive attention of researchers. It deals with uncertain data where the indeterminacy is quantified explicitly. Fuzzy computation deals with the propagation of fuzzy variables in the system. As such, fuzzy numerical techniques are tools to quantify the fuzziness. The idea of numerical methods is to convert fuzzy governing differential equations to fuzzy algebraic equations to study the fuzziness of the system.

Keywords: Interval and Fuzzy Finite Element Method, Interval and Fuzzy Differential Equations, Interval and Fuzzy Diffusion Equation, Hybrid Methods etc.

Neutrosophic Theory :-

Neutrosophic set (NS) theory is proposed by F. Smarandache, and this is generalized from the fuzzy set and intuitionistic fuzzy set. NS deals with uncertain, indeterminate, and incongruous data where the indeterminacy is quantified explicitly. This theory overcomes some limitations of the existing fuzzy theory in depicting uncertain decision information.
