The geometry of dimer models

David Cimasoni (2014)

Winter Braids Lecture Notes

Similarity:

This is an expanded version of a three-hour minicourse given at the winterschool held in Dijon in February 2014. The aim of these lectures was to present some aspects of the dimer model to a geometrically minded audience. We spoke neither of braids nor of knots, but tried to show how several geometric tools that we know and love (e.g. (co)homology, spin structures, real algebraic curves) can be applied to very natural problems in combinatorics and statistical physics. These lecture...

A survey on combinatorial optimization in dynamic environments

Nicolas Boria, Vangelis T. Paschos (2011)

RAIRO - Operations Research

Similarity:

This survey presents major results and issues related to the study of NPO problems in dynamic environments, that is, in settings where instances are allowed to undergo some modifications over time. In particular, the survey focuses on two complementary frameworks. The first one is the reoptimization framework, where an instance that is already solved undergoes some local perturbation. The goal is then to make use of the information provided by the initial solution to compute a new solution....

Lefschetz Fibrations and real Lefschetz fibrations

Nermin Salepci (2014)

Winter Braids Lecture Notes

Similarity:

This note is based on the lectures that I have given during the winter school Winter Braids IV, School on algebraic and topological aspects of braid groups held in Dijon on 10 - 13 February 2014. The aim of series of three lectures was to give an overview of geometrical and topological properties of 4-dimensional Lefschetz fibrations. Meanwhile, I could briefly introduce real Lefschetz fibrations, fibrations which have certain symmetry, and could present some...

Invariant measures and long-time behavior for the Benjamin-Ono equation

Yu Deng, Nikolay Tzvetkov, Nicola Visciglia (2014)

Journées Équations aux dérivées partielles

Similarity:

We summarize the main ideas in a series of papers ([], [], [], []) devoted to the construction of invariant measures and to the long-time behavior of solutions of the periodic Benjamin-Ono equation.

A New Mathematical Model of Syphilis

F. A. Milner, R. Zhao (2010)

Mathematical Modelling of Natural Phenomena

Similarity:

The CDC launched the National Plan to Eliminate Syphilis from the USA in October 1999 . In order to reach this goal, a good understanding of the transmission dynamics of the disease is necessary. Based on a SIRS model Breban   provided some evidence that supports the feasibility of the plan proving that no recurring outbreaks should occur for syphilis. We study in this work a syphilis model that includes partial...
