## Numerical Analysis

### MATH 4073

**Ying Wang**, Department of Mathematics

Mathematical models for modern applied sciences and engineering often consist of ordinary and partial differential equations. In most cases these problems do not have a simple explicit solution and can only be solved numerically. The construction and the accuracy of the numerical computation become vitally important. This Presidential Dream Course will expose the students to the subject through rigorous mathematical approaches.

The topics will include (but not be limited to) numerical linear algebra, single-step, multi-step, explicit and implicit numerical integrators for ordinary differential equations, and numerical methods for hyperbolic conservation laws. The focus of this course will be on the consistency, stability and convergence analysis. Students will have the opportunities to hear the state of the art of the subject from the world-class guest speakers.

### Public Lecture Series

The Department of Mathematics presents a public lecture series in conjunction with the Presidential Dream Course. **Presentations are free and open to the public**. For information or accommodation to events on the basis of disability, please contact the department of Mathematics at 405-325-6711.

**Mathematics Department, University of British Columbia

Despite the appearance sometimes given in textbooks, not all differential equations are posed on straight lines and rectangles. This talk will introduce some easy-to-use techniques for computing numerical solutions to partial differential equations posed on curved surfaces and other general domains. One application is modelling animal coat pattern formation using reaction-diffusion equations. We'll also look at some other examples such as curve evolution, bulk-surface coupling, point clouds, visual effects, image processing, and mesh generation. A brief software demo will show how you can apply these techniques to your own problems.
