Monday, October 25

PROBABILITY SEMINAR
TIME:  10:10 – 11:00 am
ROOM:  Temple 303
SPEAKER:  Professor Joan Lind
TITLE: "Holder regularity of the SLE trace"
ABSTRACT: For each k > 0, the Schramm-Loewner Evolution trace is a random two-dimensional curve. We will discuss bounds on the Holder regularity of these curves.

ALGEBRA SEMINAR
TIME:  3:35 – 4:25 pm
ROOM:  AC 113A
SPEAKER:  Amit Kaushal
TITLE: "Absolute Values on Q (part 2)
ABSTRACT: We will prove the classical result of Ostrowski that every non-trivial absolute value of Q is equivalent to either the usual one (the Archimedean case) or a p-adic one (the non-Archimedean cases).

NIMBioS SPECIAL SEMINAR
TIME:  11:00 am
ROOM:  403B, Blount Hall, 1534 White Ave.
SPEAKER:  Dave McCandlish, NIMBioS Short-Term Visitor, Dept. of Biology, Duke University
TITLE: "Evolution on the fitness landscape: A spectral approach to analysis and visualization"
Join NIMBioS for a special seminar with short-term visitor Dave McCandlish, who will be discussing the fitness landscape, which is used to visualize the relationship between genotypes and reproductive success. The fitness landscape is a classical concept in evolutionary biology, but the structure of the fitness landscape and its effects on evolutionary dynamics are difficult to understand because the space of genotypes is typically high-dimensional. McCandlish will present an approach to understanding evolution on the fitness landscape when mutation is weak so that evolution can be modeled as a Markov chain over the set of genotypes. It turns out that the eigendecomposition of the transition matrix describing this Markov chain provides a natural way of thinking about the effects of the fitness landscape on the evolutionary dynamics. This eigendecomposition also suggests a method for creating low-dimensional representations of fitness landscapes that can easily be applied to very large fitness landscapes. McCandlish will show and explore several of these visualizations.
