Lecture
This lecture introduces Dirac's notation in linear algebra, focusing on the Hilbert space over the field of complex numbers and the concept of tensor product. It covers the representation of vectors, kets, bras, and brackets, along with the properties of inner product spaces and skew symmetry. The lecture also delves into the Cauchy-Schwarz inequality, the Heisenberg uncertainty principle, and the notion of tensor product in Hilbert spaces. Additionally, it explores the basis of Hilbert spaces, the concept of orthonormal basis, and the representation of tensors. The lecture concludes with discussions on components, Sommerfeld product, and the normal basis of vectors.
