On some algebraic and extremal problems in discrete geometry
Seyed Hossein Nassajianmojarrad
In the present thesis, we delve into different extremal and algebraic problems arising from combinatorial geometry. Specifically, we consider the following problems. For any integer , we define to be the minimum positive integer such that an ...
EPFL2017Cocycle growth for the Steinberg representation
This thesis investigates the growth of the natural cocycle introduced by Klingler for the Steinberg representation. When possible, we extend the framework of simple algebraic groups over a local field to arbitrary Euclidean buildings. In rank one, the grow ...
EPFL2016Mixed strain-displacement finite elements for landslide and avalanche release prediction
Determination of the initial detaching volume is one of the major challenges in snow avalanche and debris flow forecast. Soil liquefaction due to loss of cohesion results in landslides, whereas quasi-brittle failure triggers the release of snow avalanches. ...
2015Mixed stabilized finite element methods in nonlinear solid mechanics. Part III: Compressible and incompressible plasticity
This paper presents the application of a stabilized mixed strain/displacement finite element formulation for the solution of nonlinear solid mechanics problems involving compressible and incompressible plasticity. The variational multiscale stabilization i ...
Elsevier2015The number of distinct distances from a vertex of a convex polygon
János Pach, Rom Pinchasi, Gabriel Nivasch
Erd\H{o}s conjectured in 1946 that every n-point set P in convex position in the plane contains a point that determines at least floor(n/2) distinct distances to the other points of P. The best known lower bound due to Dumitrescu (2006) is 13n/36 - O(1). I ...
