    Speaker

    Prof. Matej Filip

    Description

    We prove that Gorenstein terminal toric fourfold singularities are unobstructed. We also establish vanishing results for the obstruction space for certain Gorenstein toric Fano varieties. Finally, we discuss connections with mirror symmetry and Laurent polynomials.
