An important question in the study of Riemannian manifolds of positive sectional curvature
is how to distinguish manifolds that admit a metric with non-negative sectional
curvature from those that admit one of positive ...

Electromagnetic wave propagation in complex dispersive media is governed by the time dependent
Maxwell’s equations coupled to equations that describe the evolution of the induced macroscopic polarization.
We consider “ ...
We propose algorithms for computational upscaling of flow
from porescale (microscale) to lab scale (mesoscale). In particular, we
solve Navier-Stokes equations in complex pore geometries and average
their solutions to ...

Humans move frequently and tend to carry parasites among areas with endemic malaria and into areas where local transmission is unsustainable. Human-mediated parasite mobility can thus sustain parasite populations in area ...
Translation surfaces can be viewed as polygons with parallel and equal sides
identified. An affine homeomorphism φ from a translation surface to itself is called
pseudo-Anosov when its derivative is a constant matrix i ...
