Recovery from Power Sums

Hana Melánová, Bernd Sturmfels, Rosa Winter

We study the problem of recovering a collection of numbers from the evaluation of power sums. This yields a system of polynomial equations, which can be underconstrained ($…

Linear Spaces of Symmetric Matrices with Non-Maximal Maximum Likelihood Degree

Kathlen Kohn, Rosa Winter, Yuhan Jiang

We study the maximum likelihood degree of linear concentration models in algebraic statistics. We relate the geometry of the reciprocal variety to that of semidefinite programming.…

Fields of definition of elliptic fibrations on covers of certain extremal rational elliptic surfaces

Victoria Cantoral-Farfán, Alice Garbagnati, Cecília Salgado +2

We study K3 surfaces over a number field which are double covers of extremal rational elliptic surfaces. We provide a list of all elliptic fibrations on certain K3 surfaces tog…
