Matrix continued fractions associated with lattice paths, resolvents of difference operators, and random polynomials

J. Kim, A. López-García, V. A. Prokhorov

We begin our analysis with the study of two collections of lattice paths in the plane, denoted and . These paths consist of sequences…

Lattice paths, vector continued fractions, and resolvents of banded Hessenberg operators

Abey López-García, Vasiliy A. Prokhorov

We give a combinatorial interpretation of vector continued fractions obtained by applying the Jacobi-Perron algorithm to a vector of resolvent functions of a banded Hesse…
