At the heart of every local search procedure is a directed graph on candidate solutions (states) such that every unsatisfying state has at least one outgoing arc. In randomized local search the hope is that a random walk on the graph reaches a satisfying state (sink) quickly. We give a general algorithmic local lemma by establishing a sufficient...

Matrix, tensor, and other factorization techniques are used in a wide range of applications and have enjoyed significant empirical success in many fields. However, common to a vast majority of these problems is the significant disadvantage that the associated optimization problems are typically non-convex due to a multilinear form or other conve...

In this talk, we present the study of the regularity of solutions to somesystems of reaction€“diffusion equations, with reaction terms having asubquadratic growth. We show the global boundedness and regularity ofsolutions, without smallness assumptions, in any dimension N. The proofis based on blow-up techniques. The natural entropy of the syste...

Objects to be protected, not subjects with rights: examining the appropriation of the CRC and ACRWC in Ugandan policy In the past two decades significant attention has focused on children's rights and welfare. The adoption of the Convention on the Rights of the Child (CRC) in 1990 by all but three UN member states spawned other international, re...

Two elementary Ricker maps in the positive half-line are coupled to produce a planar mapping leaving the positive cone invariant. While this mapping appears to provide an exercise fit for a Calculus class, it is one of the most challenging problems ever experienced by the authors, namely to prove global attraction to the interior fixed point, al...
