It is an excellent introductory combined course on theory of relativity and cosmology. This is a module principally on Einstein's general theory of relativity, a relativistic theory of gravitation which explains gravitational effects as coming from the curvature of space-time. It provides a comprehensive introduction to material which is currently the subject of enthusiastic study from the theoretical and experimental standpoints. In addition, in order to understand the general theory fully, some familiarity with tensor calculus is required. This will involve some self-study material at the start of the module. The rest of the course will be devoted to a detailed investigation of the theory itself together with applications to classical black holes and cosmology.

Hydrology treats the flow of water on and below the surface of the Earth. It involves mainly water quality and treats river flood forecasting and ground water flow to wells. It also treats soil deposition, stream erosion and sediment transport. Bangladesh is a riverine country. We have many international and national rivers. Mathematical Hydrology deals with the occurrence, movement, and storage of water in the earth system. So hydrology is a very important subject for our country. The objectives of this course are to give a clear concept to students about use of Hydrology in science and water engineering fields. This course will help the student to identify surface flow, river flow, flood forecasting, measure soil erosion, channel erosion by using different kind of conceptual, mathematical and hydrodynamic.

It is an excellent introductory combined course of Finite Element Method (FEM) and Finite Difference Method (FDM). The approaches of this course are motivated by two primary considerations: audience and pedagogy. Regarding audience, the purpose is to make the method understandable and usable to people in all fields of engineering and physical sciences. Regarding pedagogy, the purpose is to make the technical derivations and explanations as lucid and as simple as possible, without being simplistic. FEM is a general and powerful numerical method, applicable to a broad variety of mathematical problems that arise in almost all areas of science and engineering. FDM is introduced in this course to solve partial differential equations approximately. To apply the FDM, all derivatives in a differential equation are replaced by approximating difference quotients. Both FEM and FDM procedure reduce the ordinary and partial differential equation problems to the system of algebraic equations.

Magnetic fields are of vital importance in astrophysics and geophysics, playing crucial roles in the dynamics of galaxies, stars (including star formation) and planets (including the Earth). Magneto-hydrodynamics (MHD) is concerned with understanding the nature of fluid flows in the presence of magnetic fields. It therefore combines electromagnetic theory with fluid dynamics. This course gives a basic introduction to MHD, detailing how magnetic fields can have significant effects on the nature of fluid flows (including the important topic of plasma confinement in fusion devices) and how fluid flows can self-consistently lead to the generation of magnetic fields via dynamo action (which is believed to be important for the maintenance of the magnetic field of both the Earth and Sun).

This course is an introduction to the beautiful theory of Riemannian Geometry, a subject with no lack of interesting examples. The core of this course will be an introduction to Riemannian geometry - the study of Riemannian metrics on abstract manifolds. This is a classical subject, but is required knowledge for research in diverse areas of modern mathematics. We will try to present the material in order to prepare for the study of some of the other geometric structures one can put on manifolds. They are indeed the key to a good understanding of it and will therefore play a major role throughout the course.

The Computational Fluid Dynamics (CFD) is an inherently interdisciplinary branch of science which has an extremely broad spectrum of applications. CFD become an essential tool in analysis and design of thermal and fluid flow systems in wide range of industries. Fluid dynamics uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Few prominent areas of applications of CFD include meteorology, transport systems (aerospace, automobile, high-speed trains), energy systems, environment, electronics, bio-medical (design of life-support and drug delivery systems), etc. There has been considerable growth in the development and application of CFD in all aspects of fluid dynamics. CFD has become a standard modeling tool widely utilized within industry. The correct use of CFD as a design analysis or diagnostic tool requires a thorough understanding of underlying physics, mathematical modeling and numerical techniques. This course aims to provide precisely these insights of CFD. Finite difference and finite volume methods will be discussed as different means of discretization of the fluid dynamics equations. A necessary theoretical background concerning accuracy, convergence, consistency, and stability of the numerical schemes will be provided.

Dynamical systems theory is the mathematical theory of time-varying systems and it is used in the modelling of a wide range of physical, biological, engineering, economic and other phenomena. This course presents a broad introduction to the area, with emphasis on those aspects important in the modelling and simulation of systems. General dynamical systems are described, along with the most basic sorts of behaviour that they can show. The dynamical systems most commonly encountered in applications are formed from sets of differential equations. The most regular kinds of behaviour-equilibrium and periodic---are the most easy to analyze theoretically; linearization about such trajectories are discussed, for periodic behaviour this is done using the Poincare’ Map. Much more complex behaviours, including chaos, may be found; these are described by means of their attractors. In applications it is often important to know how the observed behaviour changes with changes in the system parameters; such changes can often be sudden, but frequently conform to one of a relatively small number of scenarios: the study of these forms the subject of bifurcation theory. The simplest bifurcations are discussed. Many physical systems can become unstable in the sense that small disturbances superimposed on their basic state can amplify and significantly alter their initial state. In this course we introduce the basic theoretical and physical methodology required to understand and predict instability in a variety of situations with focus on hydrodynamic instabilities.
