On the behavior of the ground state energy under weak perturbation of critical quasilinear operators in
Ujjal Das, Hynek Kovařík, Yehuda Pinchover
We consider a critical quasilinear operator in perturbed by a weakly coupled potential. For , we find the leading asymptotic of the lowest…

Lieb-Thirring inequality for the 2D Pauli operator
Rupert L. Frank, Hynek Kovařík
By the Aharonov-Casher theorem, the Pauli operator has no zero eigenvalue when the normalized magnetic flux satisfies , but it does have a zero energy resonance. We…

Spectral properties and time decay of the wave functions of Pauli and Dirac operators in dimension two
Hynek Kovařík
We consider two-dimensional Pauli and Dirac operators with a polynomially vanishing magnetic field. The main results of the paper provide resolvent expansions of these operators in…
