We construct new smooth CY 3-folds with 1-dimensional Kaehler moduli by pfaffian method and determine their fundamental topological invariants. The existence of CY 3-folds with the computed invariants was previously conjectured by C. van Enckevort...

Given a nonzero integer d and a positive integer n we know, by Hermite's Theorem, that there exist only finitely many degree n number fields of discriminant d. It is thus natural to ask whether there are refinements of the discriminant which...

The boundary rigidity problem consists in determining the Riemannian metric of a compact Riemannian manifold with boundary by measuring the lengths of geodesics joining points of the boundary. The lens rigidity problem consists in determining the...

Delay is one of the most important performance measures of a communication system. In scenarios as different as mobile, ad hoc, wireless networks and content distribution networks, delay is caused by seemingly very different random phenomena, which...

Multiplicative differential forms are relevant whenever considering an object with a smooth groupoid of symmetries. One can ask what is the corresponding infinitesimal object, and in fact some of the most important examples arise from this direction...

Fred Brauer has agreed to give this informal survey talk about TB modeling. There will be a reading list advertised later on for students who would like to read up about these interesting problems.This lecture on disease modeling fits into a theme...

Atmospheric dispersion refers to the transport of contaminants in the atmosphere under the influence of advection (due to the wind) and turbulent diffusion. When the contaminant is emitted from a stationary point source, then the governing advection...

To any polynomial over a perfect field of positive characteristic, one may associate an invariant called the F-pure threshold. This invariant, defined using the Frobenius morphism on the ambient space, can be thought of as a positive characteristic...

The concept of entropy was introduced into ergodic theory by Kolmogorov in the late 1950s. It can be viewed as a measure of the average information gained in learning that the orbit of an unidentified point visits a certain sequence of sets in a...
