Tensor Analysis (Lecture 1) ।। Introduction to Tensorsbr br Here we start a series of video lectures on Tensors to cover it's full course. This is the first video from this series. In this video some basic concepts are discussed which are helpful to understand Tensors properly. The following topics are covered in this video ---- br 1.) Definition of Tensorbr 2.) Transformation of Co-ordinates between different frame of referencebr 3.) Einstein's Summation Conventionbr 4.) Free and Dummy Index br 5.
