Venerdì 4 dicembre 2020, alle ore 10,30, Roser Homs Pons (TU München) terrà un seminario dal titolo:
Primary ideals and their differential equations
Abstract: An ideal in a polynomial ring encodes a system of linear partial differential equations with constant coefficients. Primary decomposition organizes the solutions to the PDE. This paper develops a novel structure theory for primary ideals in a polynomial ring. We characterize primary ideals in terms of PDE, punctual Hilbert schemes, relative Weyl algebras, and the join construction. Solving the PDE described by a primary ideal amounts to computing Noetherian operators in the sense of Ehrenpreis and Palamodov. We develop new algorithms for this task, and we present efficient implementations.
I seminari si terranno online, sulla piattaforma Zoom.
