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...

The Hilbert scheme of projective space is a fundamental moduli space in algebraic geometry. The naive generalization of the Hilbert scheme can fail to exist for some spaces of interest, however. D. Rydh and I have generalized the Hilbert scheme, to...

Arnold tongues are parameter regions within which dynamics of a mathematical model become mode-locked to a particular frequency or period. Recent studies of models in a wide variety of fields (examples include models of spiking in neurons, the human...
