Universal Sums of Triangular Numbers and Squares
Zichen Yang
In this paper, we study universal sums of triangular numbers and squares. Specifically, we prove that a sum of triangular numbers and squares is universal if and only if it represe…

On finiteness theorems for sums of generalized polygonal numbers
Ben Kane, Zichen Yang
In this paper, we consider mixed sums of generalized polygonal numbers. Specifically, we obtain a finiteness condition for universality of such sums; this means that it suffices to…
