Abstract Algebra

Dive into the fundamental concepts of abstract algebra in this comprehensive 3.5-hour video course. Explore the foundations of modern algebra, starting with group theory and progressing through rings, fields, and vector spaces. Learn key definitions, theorems, and applications, including group properties, subgroups, cosets, Lagrange's theorem, homomorphisms, and isomorphisms. Examine specific group types such as cyclic, symmetric, and dihedral groups, as well as matrix groups and direct products. Delve into ring theory, covering integral domains, ideals, and field properties. Conclude with an introduction to vector spaces and modules, providing a solid foundation for further study in advanced mathematics.
