Differential Geometry: Course Outline (MAT 405)

Differential geometry is a mathematical discipline that uses the techniques of differential calculus, integral calculus, linear algebra and multilinear algebra to study problems in geometry.

Course Objective

At the end of this course the students will be able to understand differential geometry, its connection and significance to other areas of mathematics. Extend many of the basic concepts and tools of multivariable calculus and linear algebra to the contexts of calculus on Riemannian geometry, develop and demonstrate a level of expertise in mathematical reasoning appropriate to a challenging upper-level mathematics course.
