In this talk a lowest-degree pair of nonconforming finite elements on quadrilaterals and hexahedrons will be introduced for the approximation of the Stokes equations. Also, an equal order pair of nonconforming finite element pair will be introduced...

This is a working seminar on the homotopy theory of moduli spaces

Natural resource problems typically must be modeled using data that is often incomplete, asynchronous and collected at different spatial and temporal scales with differing levels of measurement uncertainty. Both deterministic and stochastic models...

In these talks we describe our proofs of the Hanna Neumann Conjecture. This conjecture of the late 1950's can be described both as a problem in group theory or as one in graph theory. Our first proof is longer and interprets the problem using...

Implicit time stepping applied to discretized incompressible fluid flow problems results in discrete Stokes-like (saddle-point, KKT) problems. There is a class of so-called Projection Methods in which these Stokes-like problems are efficiently...

I will present a joint work with Behrend. For any smooth projective variety, we construct a differential graded scheme (stack) structure on the moduli space of complexes of coherent sheaves. The construction uses the Hochschild cochain complex of A...

Gedrich and Gruenberg(1987)and Ikenaga(1984) studied the algebraic invariants silp ZG,the supremum of the injective lengths of the projective ZG-modules,and spli,the supremum of the projective lengths of the injective ZG-modules,in connection with...

Somitogenesis is a process for the development of somites which are transient, segmental structures that lie along the anterior-posterior axis of vertebrate embryos. The pattern of somites is traced out by the ``segmentation clock genes" which...
