In 2003, Haglundâ€™s bounce statistic gave the first combinatorial interpretation of the q, t-Catalan numbers and the Hilbert series of diagonal harmonics. In this paper we propose a new combinatorialâ€¦ (More)

An n-core partition is an integer partition whose Young diagram contains no hook lengths equal to n. We consider partitions that are simultaneously a-core and b-core for two relatively prime integersâ€¦ (More)

For each skew shape we define a nonhomogeneous symmetric function, generalizing a construction of Pak and Postnikov [9]. In two special cases, we show that the coefficients of this function whenâ€¦ (More)

Each positive rational number x > 0 can be written uniquely as x = a/(bâˆ’ a) for coprime positive integers 0 < a < b. We will identify x with the pair (a, b). In this paper we define for each positiveâ€¦ (More)

Each positive rational number x > 0 can be written uniquely as x = a/(b âˆ’ a) for coprime positive integers 0 < a < b. We will identify x with the pair (a, b). In this extended abstract we useâ€¦ (More)
