| Kurzbeschreibung | Introduction to partial differential equations. Differential equations which are important in applications are classified and solved. Elliptic, parabolic and hyperbolic differential equations are treated. The following mathematical tools are introduced: Laplace transforms, Fourier series, separation of variables, methods of characteristics. |
| Lernziel | Mathematical treatment of problems in science and engineering. To understand the properties of the different types of partial differential equations. The first lecture is on Thursday, September 29 13-15 in HG F 7 and video transmitted into HG F 5. The exercises Sheet are here: Link The coordinator is Claudio Sibilia (see https://www.math.ethz.ch/the-department/people.html?u=sibiliac) The first exercise session is on Thursday, September 22 or resp. Friday, September 23. If you would like feedback on your work, please give it to your course assistent or leave it in the box of your course assistant in HG F 27. The due Date is one week later the assignment. Office hour (Praesenz): Thursday 16-17, NO E 39. |
