Title: Generalizing Siciak’s product formula
Abstract: In pluripotential theory, the Siciak-Zakharyuta extremal functions are well studied. Siciak described how the Siciak-Zakharyuta function associated to a cartesian product relates to the Siciak-Zakharytua functions associated to each of the terms in the product. In this talk, we will discuss a generalization of Siciak’s result, using generalized Siciak-Zakharyuta functions. Other corollaries to this generalization are discussed along with showing how a weighted version is impossible.
