Let Mg be the moduli space of smooth curves of genus g. The tautological ring is a subring of the cohomology of Mg that was introduced by Mumford in the 1980s in analogy with the cohomology of Grassmannians. Work of Faber and Faber-Zagier in the 1990s led to two competing conjectural descriptions of the structure of the tautological ring. After reviewing these conjectures, I will discuss some of...   More >

Polyphosphorus units are an important class of compound and isolobal to carbon-based relatives. Because of the lone pairs at the phosphorus atoms, the five-fold symmetric cyclo-P5 ring of the pentaphosphaferrocenes [CpRFe(η5-P5)] enables the use of these complexes in unique supramolecular aggregations with Lewis acidic transition metal moieties to form unprecedented giant spherical molecules...   More >

Student 3-Manifold Seminar: The loop theorem and Dehn's lemma

Seminar | February 8 | 4-5:30 p.m. | 939 Evans Hall

 Kyle Miller, UC Berkeley

 Department of Mathematics

Simplified, the loop theorem states that if the induced map $\pi _1(\partial M)\to \pi _1(M)$ for a $3$-manifold $M$ is not injective, then there is a nullhomotopy of an essential loop in $\partial M$ that can be represented by an embedded disk. We will go through the proof of Stalling's formulation of the loop theorem using Papakyriakopoulos's tower construction and discuss some applications.
