Gamma positivity of the Excedance based Eulerian polynomial in positive elements of Classical Weyl Groups

Hiranya Kishore Dey, Sivaramakrishnan Sivasubramanian

The classical Eulerian polynomials $A_{n} (t)$ are known to be gamma positive. Define the positive Eulerian polynomial $AEx c^{+}_{n} (t)$ as the polynomial obtained when we sum…

Gamma positivity of the Descent based Eulerian polynomial in positive elements of Classical Weyl Groups

Hiranya Kishore Dey, Sivaramakrishnan Sivasubramanian

The classical Eulerian polynomials $A_{n} (t)$ are known to be gamma positive. Define the positive Eulerian polynomial $A_{n}^{+} (t)$ as the polynomial obtained when we sum descents over…
