Tensor analysis is a branch of mathematics that deals with the study of tensors, which are algebraic objects that describe linear relationships between sets of geometric objects, such as vectors and scalars. It is a fundamental subject in various fields, including physics, engineering, computer science, and mathematics. In this article, we will provide a comprehensive guide to tensor analysis problems and solutions, along with a collection of resources where you can find PDF free materials to help you master this subject.

If you are looking for resources, you are likely a student of physics or engineering trying to bridge the gap between theory and application. This guide breaks down the best free resources available, categorizes the types of problems you should look for, and provides a sample problem to demonstrate the level of difficulty you should expect.

$$\nabla_j V^i = \frac\partial V^i\partial x^j + \Gamma^i_jk V^k$$ where $\Gamma^i_jk$ are the Christoffel symbols. In flat space (Cartesian coordinates), the Christoffel symbols vanish, so $\nabla_j V^i = \partial_j V^i$.
