Expanding the unicellular LLT polynomials of two-headed melting lollipops into ribbon Schurs

Abstract

We prove a simple formula expanding the unicellular LLT polynomials of a class of graphs we call two-headed melting lollipops into ribbon Schur functions. Our work extends the Schur expansion originally found for melting lollipop graphs by Huh, Nam, and Yoo.
