Gamma-positivity is a property of polynomials that implies palindromicity and unimodality. It has received considerable attention in recent times because of Gal's conjecture, which asserts gamma-positivity of the h-polynomial of flag homology spheres. The Eulerian polynomials and the Narayana polynomials are examples of such h-polynomials that a...
