Uniform bounds for bilinear symbols with linear K-quasiconformally embedded singularity

Marco Fraccaroli, Olli Saari, Christoph Thiele

We prove bounds in the strict local $L^{2} (R^{d})$ range for trilinear Fourier multiplier forms with a $d$ -dimensional singular subspace. Given a fixed parameter $K \geq 1$ …

Phase space localizing operators

Marco Fraccaroli, Olli Saari, Christoph Thiele

We construct phase space localizing operators in all dimensions. These are frequency localized variants of the conditional expectation operator related to a dyadic stopping time. O…
