Multi-type -Wright--Fisher processes with polynomial drift: Bernstein duality, long-term behaviour, and simulation of moments
Sebastian Hummel
The -type -Wright--Fisher process with polynomial drift is a Lévy-type process on the -dimensional unit simplex whose generator entails a particular jump and diffusive…
Toric vector bundles and the number of zeros of vertical systems
Carles Checa
We provide necessary and sufficient conditions for the specializations of a vertically parametrized polynomial system to attain the maximal number of complex nonzero solutions. To…
Trivariate Splines on Fans of Hyperplane Arrangements and Koszul Homology
Carles Checa, Michael DiPasquale, Pablo Mazón +5
We study the space of splines where denotes a smoothness distribution and is the fan of a central hyperplan…
A sparse overview on sparse resultants
Carles Checa, Ioannis Z. Emiris, Christos Konaxis
In this survey, we give an overview of advances in the theory and computation of sparse resultants. First, we examine the construction and proof of the Canny-Emiris formula, which…
