A Vietoris–Smale mapping theorem for the homotopy of hyperdefinable sets

Results of Smale (Proc Am Math Soc 8(3): 604–604, 1957) and Dugundji (Fundam Math 66:223–235, 1969) allow to compare the homotopy groups of two topological spaces X and Y whenever a map f : X → Y with strong connectivity conditions on the fibers is given. We&#x...

Mini-Workshop: Surreal Numbers, Surreal Analysis, Hahn Fields and Derivations

New striking analogies between H. Hahn’s fields of generalised series with real coefficients, G. H. Hardy’s field of germs of real valued func- tions, and J. H. Conway’s field No of surreal numbers, have been lately discovered and exploited. The aim of the workshop was to...

Optimal design problems for Schrödinger operators with noncompact resolvents

We consider optimization problems for cost functionals which depend on the negative spectrum of Schr\"odinger operators of the form $-\Delta+V(x)$, where $V$ is a potential, with prescribed compact support, which has to be determined. Under suitable assumptions the existence of an&...

Continuity and estimates for multimarginal optimal transportation problems with singular costs

We consider some repulsive multimarginal optimal transportation problems which include, as a particular case, the Coulomb cost. We prove a regularity property of the minimizers (optimal transportation plan) from which we deduce existence and some basic regularity of a maximizer for the ...

Thin elastic plates supported over small areas. II. Variational-asymptotic models

An asymptotic analysis is performed for thin anisotropic elastic plate clamped along its lateral side and also supported at a small area $\theta_{h}$ of one base with diameter of the same order as the plate thickness $h\ll1.$ A three-dimensional boundary layer in the vici...
