11/6/2023 0 Comments Differential geometry surfacesSuch bending preserves Gaussian curvature so any such bending of a sphere with a region removed will also have constant Gaussian curvature. Whilst the sphere is rigid and can not be bent using an isometry, if a small region removed, or even a cut along a small segment, then the resulting surface can be bent. There are many other possible bounded surfaces with constant Gaussian curvature. do Carmo also gives three different examples of surface with constant negative Gaussian curvature, one of which is pseudosphere. either have a boundary or a singular point. You are encouraged to work together on the homework, but you should write up your own solutions individually, and you must acknowledge any collaborators.K = κ 1 κ 2. There will be a weekly homework assignment due on Friday evening. Though we will occasionally see proofs in class, Proofs & Fundamentals (Math 261) is not required. The prerequisite is Math 241 (Vector Calculus). Time permitting, we may also discuss applications to subjects such as cartography and navigation, shapes of soap bubbles, computer graphics, image processing, and general relativity. Topics covered will include curvature and torsion of curves, geometry of surfaces, geodesics, spherical and hyperbolic geometry, minimal surfaces, Gaussian curvature, and the Gauss-Bonnet theorem. This course will use methods from vector calculus to study the geometry of curves and surfaces in three dimensions. The Kindle version ought to work on Kindles, PC's, Macs, iPads, and Androids. Amazon also has a Kindle version of the book, which has excellent quality. The book is currently available for $54 from, or you can rent it for the semester for $16. You will need a copy of the textbook for reading and homework problems, though you do not need to bring it to class. The textbook is Differential Geometry of Curves and Surfaces, by Banchoff and Lovett. Here is the syllabus from the last time I taught the course. Though the course used a textbook, I also wrote outlines of some of the material we covered: Final Exam Practice Problems (and Solutions).Exam 2 Practice Problems (and Solutions).Exam 1 Practice Problems (and Solutions). The course included three in-class exams, which were worth 60% of the course grade. Homework 12 (Quadratic Forms, Principle Curvatures, Darboux Frame).Homework 11 (Maps Between Surfaces, Gauss Map, Gaussian Curvature).Homework 10 (First Fundamental Form, Hyperbolic Plane).Homework 9 (Tangent Vectors, Critical Points).Homework 8 (Manifolds and Higher Dimensions).Homework 6 (Torsion, Frenet–Serret Formulas).Homework 5 (Parametric Curves in Three Dimensions).Homework 4 (More Curvature, Line Integrals, Envelopes, Pedal Curves).Homework 3 (Parametrizations and Curvature in Two Dimensions).Homework 2 (Integration on Curves, Arc Length, Tractrix).Homework 1 (Roulettes, Parallel Curves).Students were encouraged to work together on the homework but were required to write up their own solutions individually. Here are the weekly homework assignments for the course, which were worth 40% of the course grade. The textbook for the course was Differential Geometry of Curves and Surfaces, by Banchoff and Lovett. I focused the course heavily on vector geometry and parametrizations of curves, surfaces, and manifolds, while also covering classical differential geometry topics such as curvature of curves and surfaces. The course required only multivariable calculus as a prerequisite, and most of the students who took the course were junior or senior math or physics majors. This page contains information about this course. I developed an upper-level differential geometry course for Bard College which I taught on two occasions.
