Hankel determinants for convolution powers of Motzkin numbers

Combinatorics 2025-03-03 v1 Number Theory

Abstract

We evaluate the Hankel determinants of the convolution powers of Motzkin numbers for r27r\leq 27 by finding shifted periodic continued fractions, which arose in application of Sulanke and Xin's continued fraction method. We also conjecture some polynomial characterization of these determinants.
