On Schroedinger type operators with unbounded coefficients: Generation and heat kernel estimates

Luca Lorenzi, Abdelaziz Rhandi

We consider the Schrödinger type operator $A = (1 + ∣ x ∣^{α}) Δ - ∣ x ∣^{β}$ , for $α \in [0, 2]$ and $β \geq 0$ . We prove that, for any $p \in (1, \infty)$ , the minimal realization of opera…

The Oseen-Navier-Stokes flow in the exterior of a rotating obstacle: The non-autonomous case

Tobias Hansel, Abdelaziz Rhandi

Consider the Navier-Stokes flow past a rotating obstacle with a general time-dependent angular velocity and a time-dependent outflow condition at infinity -- sometimes called an Os…
