Lower Bound for the First Steklov Eigenvalue.
(2018-07-18)
In this paper we find lower bounds for the first Steklov eigenvalue in Riemannian
n-manifolds, n = 2, 3, with non-positive sectional curvature.
Wrinkles and splay conspire to give positive disclinations negative curvature
(National Academy of Sciences, 2015-10)
Recently, there has been renewed interest in the coupling between geometry and topological defects in crystalline and striped systems. Standard lore dictates that positive disclinations are associated with positive Gaussian ...
Codimension three nonnegatively curved submanifolds with infinite fundamental group

Q curvature and gravity
(American Physical Society, 2018-11)
In this paper, we consider a family of n-dimensional, higher-curvature theories of gravity whose action is given by a series of dimensionally extended conformal invariants. The latter correspond to higher-order generalizations ...
Dynamic reduced model and stochastic aspects for PFGM curved beams with variable curvature
(Pergamon-Elsevier Science Ltd, 2021-01)
In this paper a new 1D finite element model for dynamic calculations of PGFM curved beams with variable curvature is developed. The reduced high-speed calculation model allows stochastic aspects in the dynamic of the ...
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 ...
