Abstract: Coefficientwise Hankel total positivity is an algebraic upgrading of the Stieltjes moment property. In this talk, I will present a survey of this new area. I will discuss some of the main techniques to prove these results and along with some important results.

I will end the talk by by sharing a new online collection of open problems primarily on total positivity problems in combinatorics which was launched on the occassion of the 70th birthday of Alan Sokal.
