In this talk I shall sketch some results Oliver Riordan of Oxford and I have obtained on critical probabilities in percolation. Recently, Scullard and Ziff noticed that a broad class of planar percolation models are self-dual under a simple condition...

This talk considers the conjeture that $\sum_{n

Abstract Bosonic many-body models are an important class of mathematical models that are used to study gases of bosonic particles at very low temperatures. I will introduce (i) the physical systems, (ii) one way Physicists formulate the models in...

Let x be an algebraic number and let M(x) denote its Mahler measure. If x = x1...xN the t-metric Mahler measure Mt(x) is a convenient way to study the smallest possible values of M(xn) in terms of x. In joint work with J. Jankauskas, we resolve an...

The well understood phenomenon of Anderson localization says (in its dynamical formulation) that adding random fluctuations to the potential of a Schrodinger operator will lead to the absence of wave transport for the solution of the time-dependent...

I will continue our treatment, started by Masoud last week, of Deligne's Le formalisme des cycles évanescents (SGA 7, Exposé XIII) by covering topics from Sections 1.3, 1.4 and 2.1.

The atmosphere and the oceans are the two largest and most important global commons. No one has a strong individual economic incentive to protect and preserve these vital resources. Indeed, quite the opposite! Present discussions centre mainly around...

We derive new a-priori and a-posteriori error estimates for mixed finite element discretizations of second-order elliptic problems with general Robin boundary conditions, parameterized by a non-negative parameter. Our estimates are robust in this...
