报告摘要：We introduce the binomial-Stirling-Eulerian polynomials, which encompass binomial coefficients, Eulerian numbers and two Stirling statistics: the left-to-right minima and the right-to-left minima. We investigate the $\gamma$-positivity of these polynomials from both the algebraic and the combinatorial aspects. These results extend the symmetric Eulerian identity found by Chung, Graham and Knuth, and the $\gamma$-positivity of the binomial-Eulerian polynomials first demonstrated by Postnikov, Reiner and Williams.
