On the Chern-Ricci flow and its solitons for Lie groups
(Wiley VCH Verlag, 2015-09)
This paper is concerned with Chern-Ricci flow evolution of left-invariant hermitian structures on Lie groups. We study the behavior of a solution, as t is approaching the first time singularity, by rescaling in order to ...
Higgsing M2 to D2 with gravity: N=6 chiral supergravity from topologically gauged ABJM theory
(Springer, 2011-04-01)
We present the higgsing of three-dimensional N = 6 superconformal ABJM type theories coupled to conformal supergravity, so called topologically gauged ABJM theory, thus providing a gravitational extension of previous work ...

Finding solitons
(American Mathematical Society, 2020-05)
On each solvable Lie group, there is at most one solv- soliton up to isometry and scaling. This allows us to en- dow several Lie groups that do not admit Einstein metrics (e.g., nilpotent or unimodular solvable Lie groups) ...
Curvature flows for almost-hermitian Lie groups
(American Mathematical Society, 2014-12)
We study curvature flows in the locally homogeneous case (e.g. compact quotients of Lie groups, solvmanifolds, nilmanifolds) in a unified way, by considering a generic flow under just a few natural conditions on the broad ...
Unavoidable conflict between massive gravity models and massive topological terms
(World Scientific Publ Co Pte Ltd, 2004-04-10)
Massive gravity models in (2 + 1) dimensions, such as those obtained by adding to Einstein's gravity the usual Fierz-Pauli, or the more complicated Ricci scalar squared (R-2), terms, are tree level unitary. Interesting ...

Soliton Almost Kähler Structures on 6-Dimensional Nilmanifolds for the Symplectic Curvature Flow
(Springer, 2015-10)
The aim of this paper is to study self-similar solutions to the symplectic curvature flow on 6-dimensional nilmanifolds. For this purpose, we focus our attention on the family of symplectic two- and three-step nilpotent ...
