Rings 10 Tensor products of abelian groups

YouTube • October 8, 2021 • 27:53

This lecture is part of an online course on rings and modules. We define tensor products of abelian groups, and calculate them for many common examples using the fact that tensor products preserve colimits.

Tensor Operations: Contractions, Inner Products, Outer Products

YouTube • March 27, 2019 • 10:35

In this video, I continue the discussion on tensor operations by defining the contraction, inner product, and outer product. I provide some short examples of each of these operations, which will hopefully solidify your understanding of how these operations work. Questions/requests? Let me know in the comments!

A Concrete Introduction to Tensor Products

YouTube • September 10, 2021 • 37:40

The tensor product of vector spaces (or modules over a ring) can be difficult to understand at first because it's not obvious how calculations can be done with the elements of a tensor product. In this video we give an explanation of an explicit construction of the tensor product and work through several example computations, such as finding a ...

Outer Products and Contraction of Tensors

YouTube • November 9, 2024 • 10:26

We show that any two tensors can be multiplied by an operation called outer multiplication. The resulting tensor will be a tensor whose order is the sum of the order of the two tensors. Conversely, if we have two tensors one of which has at least one contravariant component and the other has at least one covariant component, then we can ...
