Stability of the Mezard-Parisi solution for random manifolds

open access: yes, 1996
The eigenvalues of the Hessian associated with random manifolds are constructed for the general case of $R$ steps of replica symmetry breaking. For the Parisi limit $R\to\infty$ (continuum replica symmetry breaking) which is relevant for the manifold ...

Duality between Ahlfors-Liouville and Khas'minskii properties for nonlinear equations

open access: yes, 2020
In recent years, the study of the interplay between (fully) non-linear potential theory and geometry received important new impulse. The purpose of this work is to move a step further in this direction by investigating appropriate versions of ...

A Riemannian View on Shape Optimization

open access: yes, 2014
Shape optimization based on the shape calculus is numerically mostly performed by means of steepest descent methods. This paper provides a novel framework to analyze shape-Newton optimization methods by exploiting a Riemannian perspective.

Robust Hessian Locally Linear Embedding Techniques for High-Dimensional Data

open access: yesAlgorithms, 2016
Recently manifold learning has received extensive interest in the community of pattern recognition. Despite their appealing properties, most manifold learning algorithms are not robust in practical applications.

The Soliton-Ricci Flow with variable volume forms

open access: yesComplex Manifolds, 2016
We introduce a flow of Riemannian metrics and positive volume forms over compact oriented manifolds whose formal limit is a shrinking Ricci soliton. The case of a fixed volume form has been considered in our previouswork.We still call this new flow, the ...

Hessian manifolds of constant Hessian sectional curvature

open access: yesJournal of the Mathematical Society of Japan, 1995
Let \(M\) be a flat affine manifold with a flat affine connection \(D\). If \(M\) admits a Riemannian metric \(g\) such that \(g\) is locally expressed by \(g= D^2 u\), then \((M, D, g)\) is said to be a Hessian manifold. We define Hessian sectional curvatures (these correspond to holomorphic sectional curvatures for Kählerian manifolds) and construct ...
