Numerical Range and Quadratic Numerical Range for Damped Systems [PDF]

open access: yes, 2017
We prove new enclosures for the spectrum of non-selfadjoint operator matrices associated with second order linear differential equations $\ddot{z}(t) + D \dot{z} (t) + A_0 z(t) = 0$ in a Hilbert space.

Carleman estimates and unique continuation property for abstract elliptic equations

open access: yes, 2011
The unique continuation theorems for elliptic differential-operator equations with variable coefficients in vector-valued Lp-space are investigated. The operator-valued multiplier theorems, maximal regularity properties and the Carleman estimates for the

Maximal regularity and Hardy spaces

open access: yes, 2007
In this work, we consider the Cauchy problem for $u' - Au = f$ with $A$ the Laplacian operator on some Riemannian manifolds or a sublapacian on some Lie groups or some second order elliptic operators on a domain.
