High frequency wave propagation for the viscoelastic wave equation with singular memory
Haim Grebnev, Plamen Stefanov
We study high-frequency propagation for a viscoelastic wave equation with spatially dependent hereditary memory in relative-history form. The kernel may have the integrable singula…

The linearized minimal surfaces problem
Haim Grebnev, Plamen Stefanov, Gunther Uhlmann +1
We characterize the kernel of the linearization of the minimal surface problem about the Euclidean metric in a bounded smooth domain , , with the b…

The Non-Abelian X-Ray Transform on Asymptotically Hyperbolic Spaces
Haim Grebnev
In this paper we formulate and prove a gauge equivalence for unitary connections and skew-Hermitian Higgs fields of suitable regularity that are mapped to the same function under t…
