Minimal Resolutions of -divisible and -dominant Ideals
Patrick Welte, Guillermo Alesandroni
We introduce invariants we call -divisibility and -dominance, which are combinatorial constraints on the minimal generators of monomial ideals. We then prove that (respec…
Sharp lower bounds for the periodic maximal Schrödinger operator in higher dimensions
Inbo Gottlieb Fenves, Jiahao Tan
We prove sharp lower bounds for the Schrödinger maximal function on the torus T^d for all dimensions d at least 2, and as a corollary obtain sharp regularity conditions for pointwi…
Maximal estimates for perturbations of the Schrödinger operator on
Inbo Gottlieb Fenves, Jiahao Tan
We study maximal estimates for exponential sums associated to graph hypersurfaces, motivated by Schrödinger maximal estimates on . We show th…
Cusp Excursions, Lattice Points on Manifolds, and the Mizohata-Takeuchi Conjecture
Inbo Gottlieb Fenves
We prove new logarithm laws for cusp excursions in spaces of lattices, and produce quantitative lower bounds for lattice points near submanifolds, using tools from dynamics and the…
