Foundations of Computational Commutative Algebra and Algebraic Geometry

How do we bridge the gap between abstract algebra and concrete geometric shapes? While classical algebraic geometry often feels highly theoretical, computational approaches allow us to solve real-world polynomial systems algorithmically. This course provides a clear, step-by-step introduction to the computational side of commutative algebra and algebraic geometry, transforming abstract proofs into practical computational techniques. By reading through this comprehensive text-only course, you will develop a strong mathematical intuition for how algebraic equations define geometric objects. You will transition from basic definitions to executing powerful algebraic algorithms, gaining the skills needed to analyze complex multi-variable polynomial systems. What you'll learn: - Understand the core terminology of polynomial rings, ideals, and affine varieties. - Master the theory and execution of Buchberger's algorithm to compute Gröbner bases. - Apply elimination theory to solve systems of non-linear polynomial equations. - Analyze the relationship between algebraic ideals and geometric coordinate rings. - Explore modern applications of computational algebra in cryptography, robotics, and data science. - Practice solving algebraic problems through structured, step-by-step written exercises. This course begins with foundational definitions of rings, fields, and ideals before introducing computational tools like Gröbner bases.
