Regularity of Solutions of the Nonlinear Sigma Model with Gravitino
TL;DR: In this article, the authors propose a geometric setup to study analytic aspects of a variant of the super symmetric two-dimensional nonlinear sigma model with gravitino fields, which extends the functional of Dirac-harmonic maps by gravity fields.

Ollivier-Ricci curvature and the spectrum of the normalized graph Laplace operator
TL;DR: In this article, the Ollivier-Ricci curvature of the normalized Laplace operator on a neighborhood graph was shown to be 1 + (1- k[t]) √ 2-k.
Evolving Networks with distance preferences
TL;DR: Simulation results for network parameters like the first eigenvalue of the graph Laplacian, clustering coefficients, average distances, and degree distributions for different distance preferences and compare them with the parameter values for random and scale-free networks find that for the shortest distance rule, a power-law degree distribution is obtained.
Multiplicity results for the two-vortex Chern-Simons Higgs model on the two-sphere
TL;DR: In this article, a Ginzburg-Landau type functional on S2 with a 6th order potential and the corresponding selfduality equations is considered, and the limiting behavior in the two vortex case when a coupling parameter tends to zero is investigated.
Non-cooperative game theory in biology and cooperative reasoning in humans.
TL;DR: An analysis of the process leading to cooperation in terms of rationality concepts, game theory and epistemic logic is developed to understand why cooperation is possible and what kind of reasoning and beliefs would lead to cooperative decision-making.
