Points of constancy of the periodic linearized Korteweg--deVries equation

Peter J. Olver, Efstratios Tsatis

We investigate the points of constancy in the piecewise constant solution profiles of the periodic linearized Korteweg--deVries equation with step function initial data at rational…

On Holographic Defect Entropy

John Estes, Kristan Jensen, Andy O'Bannon +2

We study a number of (3+1)- and (2+1)-dimensional defect and boundary conformal field theories holographically dual to supergravity theories. In all cases the defects or boundaries…

Holographic Wilson Loops, Dielectric Interfaces, and Topological Insulators

John Estes, Andy O'Bannon, Efstratios Tsatis +1

We use holography to study (3+1)-dimensional N=4 supersymmetric SU(Nc) Yang-Mills theory (SYM) in the large-Nc and large coupling limits, with a (2+1)-dimensional interface where t…

Brane embeddings in sphere submanifolds

Nikos Karaiskos, Konstadinos Sfetsos, Efstratios Tsatis

Wrapping a D(8-p)-brane on AdS_2 times a submanifold of S^{8-p} introduces point-like defects in the context of AdS/CFT correspondence for a Dp-brane background. We classify and wo…

Flow by mean curvature inside a moving ambient space

Annibale Magni, Carlo Mantegazza, Efstratios Tsatis

We show some computations related to the motion by mean curvature flow of a submanifold inside an ambient Riemannian manifold evolving by Ricci or backward Ricci flow. Special emph…

Mean Curvature Flow on Ricci Solitons

Efstratios Tsatis

We study monotonic quantities in the context of combined geometric flows. In particular, focusing on Ricci solitons as the ambient space, we consider solutions of the heat type equ…
