Mathematics and Its Applications

Mathematics 101 Dunbar, Staff

3 credits

This course develops the mathematical and quantitative skills required of an effective citizen in our complex society. The emphasis is on the interpretation of material utilizing mathematics, as opposed to the development of simple numerical skills. Possible topics include the application of elementary algebra to common practical problems; exponential growth, with applications to financial and social issues; an introduction to probability and statistics; and the presentation and interpretation of graphically presented information. Instruction in the uses of a scientific calculator and of a computer to facilitate calculations is an integral part of the course. Prerequisites: Adequate performance on the mathematics placement exam or completion of Math 099.

This course is generally offered every semester.

Algebraic Geometry

Mathematics 326T Wynne

4 credits

Algebraic geometry is the study of algebraic varieties, sets of zeros of polynomials such as curves in the plane or curves and surfaces in space. This course is an introduction to such varieties in n-dimensional space. Such a study leads naturally to the study of a certain type of set of polynomials, namely an ideal. We establish a dictionary between an ideal and the variety consisting of the set of common zeros of all the polynomials in the ideal. For example, a curve might be the intersection of two surfaces; then, each of these two surfaces has a corresponding ideal and these two ideals together generate the ideal of the curve in the intersection. We study these ideals from a theoretical and computational point of view. We describe the dictionary between polynomial ideals and affine algebraic sets. To be able to produce examples, we introduce the classification of ideals by means of Groebner bases. These give a constructive way to prove the Hilbert Basis Theorem, characterizing all algebraic varieties as intersections of a finite set of hypersurfaces. With these tools, we prove the Hilbert Nullstellensatz, and we establish the dictionary described earlier. Several applications are possible if time permits. Since the examples are computationally difficult, some time will be spent on Maple software and computer solutions and algorithms for computing Groebner bases. Prerequisite: Mathematics 220.

Hyperbolic Geometry

Mathematics 352T Dunbar

4 credits

Hyperbolic geometry, sometimes called non-Euclidean geometry, was discovered independently by Gauss, Bolyai, and Lobachevski in the 19th century as a way of finally demonstrating that the parallel postulate of plane geometry is not a logical consequence of the other postulates. After the development of special relativity by Einstein, hyperbolic geometry found another use as one of several alternative models for the large-scale geometry of the universe. The philosophy of the course is to understand hyperbolic geometry via a close study of its symmetries. This will involve some of the basic concepts of abstract algebra and complex analysis (which will be explained as they are needed). Topology also enters the picture, since the vast majority of surfaces can be thought of as pasted-together hyperbolic polygons (in the same way that a cylindrical surface can be obtained by pasting together two opposite edges of a piece of paper). Thus, hyperbolic geometry serves as the meeting ground for many different kinds of mathematics. Prerequisites: Mathematics 220 and 221.
