Título: ON THE FREENESS OF AN EXTENDED LOGARITHMIC TANGENT SHEAF FOR TORIC VARIETIES
Resumo: In this talk, I will present an extension for toric geometry of the logarithmic tangent sheaf developed by Faenzi, Jardim and Vallès in [1]. Then I will provide a connection of this sheaf to the theory of distributions and finally, I will show a criterion, for one homogeneous polynomial, to decide when the extended logarithmic tangent sheaf is free which classically is known as the Saito’s criterion.
