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 $K \geq 1$ …

A stability result for parabolic measures of operators with singular drifts

Simon Bortz, Moritz Egert, Olli Saari

We study the operator \[ \partial_t - \text{div} A \nabla + B \cdot \nabla \] in parabolic upper-half-space, where $A$ is an elliptic matrix satisfying an oscillation condition and…
