Proof of a conjecture on Hankel determinants for Dyck paths with restricted peak heights

For any integer m≥2 and r∈{1,…,m}, let fnm,r denote the number of n-Dyck paths whose peak's heights are im+r for some integer i. We find the generating function of fnm,r satisfies a simple algebraic functional equation of degree 2. The r=m case is particularly nice and we give a combinatorial p...
