1 I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you. I loafe and invite my soul. Educator Crackers. Educator brand crackers were produced in Boston from 1885 through the 1980s. They were a direct early competitor to the National Biscuit.

CANCELLED Dr. Tye Lidman North Carolina State University Left-orderability and Three-manifolds Friday, October 7, 2016, 4:00pm Ungar Room 402 Abstract: A group is called left-orderable if it can be given a left-invariant total order. We will discuss the question of when the fundamental group of a three-manifold Y is left-orderable. Orderability is known to be related to certain topological aspects of Y, such as the surfaces which sit inside it. We will discuss a conjectural relationship between left-orderability and the solutions to a certain nonlinear PDE on Y.

CANCELLED Dr. Eugene Gorsky Stony Brook University Compactified Jacobians, q,t-Catalan Numbers and Knot Invariants Thursday, November 1, 2012, 5:00pm Ungar Room 402 Abstract: Campillo, Delgado and Gusein-Zade proved that the semigroup of a plane curve singularity encodes the information about the Alexander polynomial of its link. Oblomkov and Shende conjectured an extension of their result to to the HOMFLY polynomial, which uses the Hilbert schemes and compactified Jacobians of a singular curve.

I will explain the combinatorics of their construction in the simplest example of torus knots, and relate it to the generalization of q,t-Catalan numbers of Garsia and Haiman. The talk is based on joint work with M. Fernando Schwartz University of Tennessee Geometric Inequalities for Hypersurfaces Thursday, October 11, 2012, 5:00pm Ungar Room 402 Abstract: We revisit some classic estimates for the capacity as well as a version of the Alexandrov-Fenchel inequality for hypersurfaces of Euclidean space.

We provide new, more general proofs of these inequalities, and include some rigidity statements. The results are joint work with Alexandre Freire. Professor Lars Andersson Albert Einstein Institute Max Planck Institute for Gravitational Physics Cosmological Models and Stability Thursday, October 4, 2012, 5:00pm Ungar Room 402 Abstract: In this talk I will discuss some mathematical results on inhomogeneous cosmological models, focusing on late time behavior and the issues of nonlinear stability versus instability. Professor Fernando Coda Marques IMPA, Brazil Min-max Minimal Surfaces and the Willmore Conjecture Monday, April 30, 2012, 4:00pm Ungar Room 402 Abstract: In 1965, T. Willmore conjectured that the integral of the square of the mean curvature of a torus immersed in Euclidean three-space is at least 2π 2.

Download Setting Macro X7 Sg No Miss Ltd there. In this talk we will discuss a proof of this conjecture that uses the min-max theory of minimal surfaces. This is a joint work with Andre Neves of Imperial College (UK).

Professor Ernesto Lupercio Center for Research and Advanced Studies of the National Polytechnic Institute (Cinvestav-IPN) Virtual Orbifold Cohomology Wednesday, April 25, 2012, 4:00pm Ungar Room 402 Abstract: In this talk of a mostly expository nature I will explain the orbifolding procedure for topological field theories and a new family of examples. I will first introduce the concept of topological field theory and orbifold. This is joint with Gonzalez, Segovia, and Uribe. Sebastian Schreiber University of California, Davis Should I Stay or Should I Go? An SDE Perspective on the Ecology and Evolution of Movement Friday, March 30, 2012, 5:00pm Ungar Room 402 Abstract: All populations, whether they be plants, animals, or viruses, live in spatially and temporally variable environments. Understanding how this variability influences population persistence and the evolution of movement is a fundamental issue of practical and theoretical importance in population biology. Prior work (including important contributions due to Chris Cosner and Steve Cantrell) has shown that spatial variability, in and of itself, enhances persistence and selects against random movement as well as movement into sink habitats (places unable to harbor a self-sustaining population).

Alternatively, temporal variability, in and of itself, inhibits persistence and exerts no selective pressures on movement. The combined effects, however, of spatial and temporal variability are remarkably complex. This combined variability can select for movement into sink habitats and allow for populations to persist in landscapes comprised solely of sink habitats. In this talk, I will discuss recent analytic results in which populations living in patchy environments are modeled using stochastic differential equations (SDEs).

Part of this work was done in collaboration with Steve Evans (Berkeley), Peter Ralph (Davis), and Arnab Sen (Cambridge). Ryan Derby-Talbot Quest University Are Complicated 3-manifolds Complicated? Thursday, March 29, 2012, 5:00pm Ungar Room 402 Abstract: In this talk we will discuss several ways that one can construct 3-manifolds (shapes like our spatial universe), and various ways that these constructions can be ma.
