Course Outline & Outcome:This course is specifically designed for advanced UG and PG level students in Mathematics and Physics. Wewill start with the basic idea of tensors as a generalization of vectors. We will then gradually move on tolearn the details of algebraic operations on the tensors along with the transformation laws. Then we willproceed to the core topic of tensor calculus and study the ideas like metric tensors, curvature and derivativesof tensors with adequate examples. Finally, we will delve deeper into the course where the applications oftensor calculus in different fields of Physics, especially in Special & General Theory of Relativity andCosmology will be discussed in details with some elaborate demonstrations. This course will enable thestudents to learn about the modern-day research topics such as Relativity and Cosmology and to acquire thenecessary tools which will surely help them in their future fields of research. Certificates will be issued at theend of the Course to the successful participants.
