Journal ArticleDOI
Cluster expansion for abstract polymer models
Roman Kotecký,David Preiss +1 more
TL;DR: In this article, a new direct proof of convergence of cluster expansions for polymer models is given in an abstract setting, without relying on Kirkwood-Salsburg type equations or "combinatorics of trees".
Journal ArticleDOI
Geometry of measures in $\mathbf{R}^n$: Distribution, rectifiability, and densities
Journal ArticleDOI
Differentiability of Lipschitz functions on Banach spaces
TL;DR: The main result of as discussed by the authors is that if the norm of a Banach space E is differentiable (Frechet, Gateaux, or in some intermediate sense) away from the origin, then every locally Lipschitz function defined on an open subset G of E is also differentiable at every point of G dense in G.
Journal ArticleDOI
A general mountain pass principle for locating and classifying critical points
Nassif Ghoussoub,David Preiss +1 more
TL;DR: A general "Mountain Pass" principle that extends the theorem of Ambrosetti-Rabinowitz and gives more information about the location of critical points, is established in this paper.
Journal ArticleDOI
Affine Approximation of Lipschitz Functions and Nonlinear Quotients
TL;DR: In this paper, a complete characterization of the spaces X, Y for which any Lipschitz function from X to Y can be approximated by affine functions is obtained.
