Hillclimbing saddle point inflation [PDF]
Recently a new inflationary scenario was proposed in [1] which can be applicable to an inflaton having multiple vacua. In this letter, we consider a more general situation where the inflaton potential has a (UV) saddle point around the Planck scale. This

A new generalized shift-splitting method for nonsymmetric saddle point problems
Recently, Huang and Huang [ Journal of Computational and Applied Mathematics , 328 (2018) 381–399] proposed a modified generalized shift-splitting preconditioned (denoted by MGSSP) method for solving large sparse saddle point problems, and gave the ...

Saddle point localization of molecular wavefunctions. [PDF]
AbstractThe quantum mechanical description of isomerization is based on bound eigenstates of the molecular potential energy surface. For the near-minimum regions there is a textbook-based relationship between the potential and eigenenergies. Here we show how the saddle point region that connects the two minima is encoded in the eigenstates of the model

Saddle point criteria for semidefinite semi-infinite convex multiobjective optimization problems [PDF]
In this paper, we consider a nonlinear semidefinite semi-infinite convex multiobjective optimization problem where the feasible region is determined by finite number of equality and infinite number of inequality constraints.

Saddle point states and energy barriers for vortex entrance and exit in superconducting disks and rings [PDF]
The transitions between the different vortex states of thin mesoscopic superconducting disks and rings are studied using the non-linear Ginzburg-Landau functional.

We extend known saddlepoint tail probability approximations to multivariate cases, including multivariate conditional cases. Our first approximation applies to both continuous and lattice variables, and requires the existence of a cumulant generating function.

Kaczmarz method for saddle point systems [PDF]
The Kaczmarz method is presented for solving saddle point systems. The convergence is analyzed. Numerical examples, compared with classical Krylov subspace methods, SOR-like method (2001) and recent modified SOR-like method (2014), show that the Kaczmarz
