Speaker: Prof. Jean-Claude Yakoubsohn
• 4:00 PM 5:30 PM
Sequences, differential equations and billiards 1h 30m

I will present a joint work with Jasmin Raissy. In particular, I will show how the study of sequences of complex numbers satisfying the recursion $(x_{n+1},y_{n+1})=(x_n+y_n^2,y_n+x_n^2)$ which is the step-$1$ Euler's method of the differential equation $(x',y')=(y^2,x^2)$ relates to the study of trajectories in a equilateral triangular billiard.

Speaker: Prof. Xavier Buff
