Foundations of Modern Algebra: Groups, Geometry, and Linear Spaces

Abstract algebra is the language of symmetry, structure, and modern mathematical thought. This course bridges the gap between basic computational mathematics and structural reasoning, giving you a clear pathway to understand the deep systems that power cryptography, computer science, and advanced physics. You will transition from simply calculating numbers to analyzing the fundamental rules that govern mathematical operations. Through clear written explanations, you will learn to think like a mathematician and build a rigorous foundation in abstract structures. What you'll learn: - Learn the foundational definitions of groups, subgroups, cyclic groups, and cosets. - Understand the relationship between algebraic structures, geometric symmetry, and transformations. - Explore linear algebra concepts, including vector spaces, bases, and linear transformations from an abstract perspective. - Practice constructing and reading mathematical proofs through structured, step-by-step written examples. - Discover modern applications of abstract algebra in error-correcting codes and cryptography. The course begins with essential terminology and the basic properties of sets and operations before moving systematically into group theory, matrix groups, and linear spaces. It is designed specifically for beginners, self-learners, and computer science students who have a basic grasp of high school algebra but no prior experience with higher-level abstract mathematics.
