Speaker: Venkatesan Guruswami, UC Berkeley Title: Long common subsequences between bit-strings and the zero-rate threshold of deletion-correcting codes Abstract: Suppose we transmit n bits on a noisy channel that deletes some fraction of the bits arbitrarily. What’s the supremum p* of deletion fractions that can be corrected with a binary code of non-vanishing rate? Evidently p* is at […] |

Member Seminar Speaker: Sergiy Verstyuk Title: Machine Learning the Gravity Equation for International Trade Abstract: We will go through modern deep learning methods and existing approaches to their interpretation. Next, I will describe a graph neural network framework. You will also be introduced to an economic analog of gravity. Finally, we will see how these […] |

Cobordism and Deformation Class of the Standard Model and Beyond: Proton Stability and Neutrino Mass
Cobordism and Deformation Class of the Standard Model and Beyond: Proton Stability and Neutrino Mass
Member Seminar Speaker: Juven Wang Title: Cobordism and Deformation Class of the Standard Model and Beyond: Proton Stability and Neutrino Mass Abstract: ‘t Hooft anomalies of quantum field theories (QFTs) with an invertible global symmetry G (including spacetime and internal symmetries) in a d-dim spacetime are known to be classified by a d+1-dim cobordism group TPd+1(G), […] |

Speaker: David Nelson, Harvard University Title: Statistical Mechanics of Mutilated Sheets and Shells Abstract: Understanding deformations of macroscopic thin plates and shells has a long and rich history, culminating with the Foeppl-von Karman equations in 1904, a precursor of general relativity characterized by a dimensionless coupling constant (the “Foeppl-von Karman number”) that can easily reach vK […] |
