We are dedicated to making mathematics accessible and fun to all Cornell students, and to enhancing the experience of undergraduate math study.
We organize:

Various talks given by Cornell students and faculty

Weekly meetings in Mallot 5th Floor Lounge (Mallot 532) 6pm on Thursdays consisting of puzzles or game sessions, always with pizza.

Annual Kieval Lectures delivered by prominent mathematicians from other institutions.

Other miscellanious mathy undergraduaty events.

COVID19 UPDATE: We are still meeting weekly at 6pm EDT. The meetings are now on Zoom, the link to which is emailed to the listserve every week. To join the listserve email ebs95@cornell.edu.

It is hypothesized that as a result of the buildup of greenhouse gases in the atmosphere, as early as within the next few centuries a sixth mass extinction will occur. Because the oceans absorb 30% of carbon (a greenhouse gas) emissions released into the atmosphere, they are key components in understanding both past and future climate events. In this talk, we will examine an oceanic carbon cycle model, and the implications of the results regarding a potential mass extinction.

Poincar\'e's Last Geometric Theorem states that if $T:A\rightarrow A$ is any any areapreserving homeomorphism of the annulus $A$ which ``twists'' the inner and outer boundaries of $A$ in opposite directions, then $T$ has at least two fixed points. Poincar\'e was originally interested in this result because it implies the existence of periodic orbits in the three body problem. He proved several special cases of the theorem via intuitive geometric arguments, however later complete proofs lost much of this geometric flavor. We extend Poincar\'e's argument to the general case of the theorem, while maintaining strong emphasis on his original geometric constructions. Joint work with Professor John Hubbard.

Given a ring $R$, a map $\delta:R\rightarrow R$ is a derivation if it is additive and satisfies the Leibniz rule ($\delta(ab)=\delta(a)b+a\delta(b)$ for all $a,b\in R$). It is well known that the set of derivations on a ring, denoted $\text{Der}(R)$, form a Lie ring (i.e. $\text{Der}(R)$ is closed under addition and lie brackets $[\delta_1,\delta_2]=\delta_1\circ\delta_2\delta_2\circ\delta_1$), but are typically not closed under composition. Take for instance the formal derivative on polynomials of $x$; the double derivative doesn't satisfy the Leibniz rule. We would like to study the cases when they are closed under composition (i.e. $\Der(R)$ forms a ring) with a particular focus on finite rings.
