PROJ | Visualize Riemann surfaces for the functions F(z) = f(z) + 1/f(z), where f(z) = ((z2 − 1)1/2 − z)1/3, and G(z) = arctan z (with clear indication of branching points (e.g., surface for arcsin z from Wikipedia is incomprehensible)). As an example, here are two visualizations of Riemann surface for √1 − z2 (you can check by tracking how parts I, II, III, and IV are connected that the two pictures give the same surface). Here are visualizations of Riemann surface for arcsin z. This project is for MATH 524 students. MATH 424 students can get 12 points from the project (grading is 6 points per surface, no partial credit). due May 1 |
