We consider lattice walks inℝ kconfined to the region 0 < x 1 < x 2 … < x kwith fixed (but arbitrary) starting and end points. These walks are assumed to be such that their number can be counted using a reflection principle argument. The main results are asymptotic formulas for the total number of walks of length n with either a fixed or a free end point for a general class of walks as n tends to infinity. As applications, we find the asymptotics for the number of k ‐non‐crossing tangled diagrams as well as asymptotics for two k ‐vicious walkers models subject to a wall restriction. © 2012 Wiley Periodicals, Inc.
