Resumen de Mass-critical inverse Strichartz theorems for 1d Schrödinger operators

Casey Jao, Rowan Killip, Monica Visan

• We prove inverse Strichartz theorems at L2 regularity for a family of Schrödinger evolutions in one space dimension. Prior results rely on spacetime Fourier analysis and are limited to the translation-invariant equation i∂tu=−12Δu. Motivated by applications to the mass-critical Schrödinger equation with external potentials (such as the harmonic oscillator), we use a physical space approach.
