Introduction to Plane Algebraic Curves

Employs proven conception of teaching topics in commutative algebra through a focus on their applications to algebraic geometry, a significant departure from other works on plane algebraic curves in which the topological-analytic aspects are stressed §Requires only a basic knowledge of algebra, with all necessary algebraic facts collected into several appendices§Studies algebraic curves over an algebraically closed field K and those of prime characteristic, which can be applied to coding theory and cryptography§Covers filtered algebras, the associated graded rings and Rees rings to deduce basic facts about intersection theory of plane curves, applications of which are standard tools of computer algebra§Examples, exercises, figures and suggestions for further study round out this fairly self-contained textbookThis work treats an introduction to commutative ring theory and algebraic plane curves, requiring of the student only a basic knowledge of algebra, with all of the algebraic facts collected into several appendices that can be easily referred to, as needed.§Kunz's proven conception of teaching topics in commutative algebra together with their applications to algebraic geometry makes this book significantly different from others on plane algebraic curves. The exposition focuses on the purely algebraic aspects of plane curve theory, leaving the topological and analytical viewpoints in the background, with only casual references to these subjects and suggestions for further reading.§Most important to this text:§Emphasizes and utilizes the theory of filtered algebras, their graduated rings and Rees algebras, to deduce basic facts about the intersection theory of plane curves§Presents residue theory in the affine plane and its applications to intersection theory§Methods of proof for the Riemann Roch theorem conform to the presentation of curve theory, formulated in the language of filtrations and associated graded rings§Examples, exercises, figures and suggestions for further study round out this fairly self-contained textbook§-----§From a review of the German edition:§"[T]he reader is invited to learn some topics from commutative ring theory by mainly studying their illustrations and applications in plane curve theory. This methodical approach is certainly very enlightening and efficient for both teachers and students The whole text is a real masterpiece of clarity, rigor, comprehension, methodical skill, algebraic and geometric motivation highly enlightening, motivating and entertaining at the same time One simply cannot do better in writing such a textbook."§--Zentralblatt MATHThis work treats an introduction to commutative ring theory and algebraic plane curves, requiring of the student only a basic knowledge of algebra, with all of the algebraic facts collected into several appendices that can be easily referred to, as needed.§Kunz's proven conception of teaching topics in commutative algebra together with their applications to algebraic geometry makes this book significantly different from others on plane algebraic curves.
