Every compact connected 2-manifold N can be expressed as the orbit space determined by a group of isometries G acting freely and properly discontinuously on a Riemannian 2-manifold M which is either the 2-sphere, the Euclidean plane, or the Poincaré disk. In each case, M is simply connected, and so the fundamental group of N is isomorphic to G.

Plasmonic structures are made of dielectrics and metals, and at optical frequencies metals exhibit unusual electromagnetic properties like a negative dielectric permittivity whereas dielectrics have a positive one. This change of sign allows the propagation of electromagnetic surface waves at the metal-dielectric interface, where strange phenomena appear if it presents corners.

William Kirwan *Special Faculty Meeting* Covell 216

Dr. Kirwan will meet with math, statistics and education faculty to talk about specific challenges, opportunities and responsibilities that these departments have regarding student success.

Asking, how can math education evolve to meet the urgent needs of a 21st century education?, Kirwan, executive director of the national reform effort “Transforming Post-Secondary Education in Mathematics” will present evidence-based pedagogies that offer hope for greater student access and success, even in a time of diminishing public investment in higher education.
