Daniele Taufer (Univ. K. Leuven) - Natural apolar schemes across algebra, geometry, and computations

Natural apolar schemes across algebra, geometry, and computations
Abstract: Symmetric order-d tensors (equiv. homogeneous degree-d polynomials) admit infinitely many additive decompositions by means of possibly simpler components.
To each such decomposition, one can canonically associate a zero-dimensional scheme that remembers the core geometrical information about the starting decomposition.
In this talk, we will discuss how to abstractly define and explicitly construct such geometrical objects.
On the theoretical side, we will observe that these schemes enjoy beautiful algebraic properties that are still a field of open research.
Computationally, these features may be exploited to investigate (additive) symmetric tensor decomposition, and we will look at examples of such applications.
This is based on a joint work with A. Bernardi and A. Oneto.
