Non-intersecting squared Bessel paths and multiple orthogonal polynomials for modified Bessel weights

A. B. J. Kuijlaars, A. Martinez-Finkelshtein, F. Wielonsky

We study a model of $n$ non-intersecting squared Bessel processes in the confluent case: all paths start at time $t=0$ at the same positive value $x=a$, remain positive, and ar…
