Tales from the Data Trenches of Display Advertising

May 15, 2015

Claudia Perlich

As Chief Scientist at Dstillery, Claudia Perlich works to collect about 10 billion user events daily, representing the digital and geo-physical journeys of millions of people on desktops, tablets, and mobile phones. In this lecture, Perlich will...

In Search Of: Failed Supernovae

May 12, 2015

Christopher Kochanek

Failed supernovae, where core collapse leads to the formation of a black hole without an external supernova, have always been one of the possible outcomes when a massive star dies. The observed properties of the dying, progenitor stars, mismatches...

Our Mathematical Universe

May 08, 2015

Max Tegmark

In this lecture, Tegmark surveys how humans have repeatedly underestimated not only the size of the cosmos, but also the power of the human mind to understand it using mathematical equations. He explores how mathematics in physics has allowed us to...

Bernoulli convolutions for algebraic parameters

May 08, 2015

Peter Varju

The Bernoulli convolution with parameter $\lambda$ is the law of the random variable: $\sum X_i \lambda^i$, where $X_i$ are independent unbiased $+1/-1$ valued random variables. If $\lambda 1/2$, then the Bernoulli convolution is singular and is...

Reductions of Galois representations of small slopes

May 07, 2015

Eknath Ghate

We investigate the shape of the reduction of certain crystalline Galois representations of integral slope 1 and of fractional slopes in (1,2). The proof uses the compatibility between the p-adic and mod p Local Langlands Correspondences with respect...

The GeV Sun

May 05, 2015

Annika Peter

The Sun does not shine at GeV energies on its own power, but because cosmic rays interact with its matter and light. By observing and modeling these interactions in and near the Sun, one may learn about cosmic-ray propagation in the inner...

Is the Abstract Mathematics of Topology Applicable to the Real World?

May 01, 2015

Robert D. MacPherson; Randall D. Kamien; Raúl Rabadán

Topology is the only major branch of modern mathematics that wasn't anticipated by the ancient mathematicians. Throughout most of its history, topology has been regarded as strictly abstract mathematics, without applications. However, illustrating...

Derived categories of cyclic covers and their branch divisors

April 29, 2015

Alexander Perry

Given a variety $Y$ with a rectangular Lefschetz decomposition of its derived category, I will discuss an interesting relation between the derived categories of a cyclic cover of $Y$ and its branch divisor. As examples, I will describe the cases of...

Heavy Element Synthesis in the Universe

April 28, 2015

Enrico Ramirez-Ruiz

The source of about half of the heaviest elements in the Universe has been a mystery for a long time. Although the general picture of element formation is well understood, many questions about the nuclear physics processes and particularly the...
