First Collision time of three random walks

Sunday, October 27, 2024, 2:45 -- 15:15

In this talk, we discuss the finiteness of the expected value of the first collision time of three random walks and obtain an upper bound to the expected value if terms of the starting positions of the walks. The result is expected to simplify the computations of the estimates of the number of paths for convergence of the family of such walks to the corresponding limit.

This is a joint work with Maruf Alam Tarafar.
