On August 19-20, 2019 the CMSA hosted the fifth annual Conference on Big Data. The Conference will featured many speakers from the Harvard community as well as scholars from across the globe, with talks focusing on computer science, statistics, math and physics, and economics. The talks will take place in Science Center Hall D, 1 Oxford Street. […]
From April 29 to May 1, 2019 the CMSA will be hosting a Conference on Algebraic Geometry, Representation theory and Mathematical Physics. This workshop is organized by Bong Lian (Brandeis) and Artan Sheshmani (CMSA) . The workshop will be held in room G10 of the CMSA, located at 20 Garden Street, Cambridge, MA. Videos Speakers: Dan Abramovich, Brown Roman […]
As part of the program on Mathematical Biology a workshop on Invariance and Geometry in Sensation, Action and Cognition will take place on April 15-17, 2019. Legend has it that above the door to Plato’s Academy was inscribed “Μηδείς άγεωµέτρητος είσίτω µον τήν στέγην”, translated as “Let no one ignorant of geometry enter my doors”. While geometry and invariance has […]
Speaker: Pietro Veronesi (University of Chicago) Title: Inequality Aversion, Populism, and the Backlash Against Globalization Abstract: Motivated by the recent rise of populism in western democracies, we develop a model in which a populist backlash emerges endogenously in a growing economy. In the model, voters dislike inequality, especially the high consumption of "elites." Economic growth exacerbates inequality due to […]
Speaker: Sarah Moshary (University of Chicago) Title: Deregulation through Direct Democracy: Lessons from Liquor Abstract: This paper examines the merits of state control versus private provision of spirits retail, using the 2012 deregulation of liquor sales in Washington state as an event study. We document effects along a number of dimensions: prices, product variety, convenience, substitution to other goods, […]
Speaker: Tatyana Sharpee (Salk Institute for Biological Studies) Title: Hyperbolic geometry of the olfactory space Abstract: The sense of smell can be used to avoid poisons or estimate a food’s nutrition content because biochemical reactions create many by-products. Thus, the presence of certain bacteria in the food becomes associated with the emission of certain volatile compounds. This perspective suggests that […]
Speaker: Sonia Jaffe (Microsoft) Title: Quality Externalities on Platforms: The Case of Airbnb Abstract: We explore quality externalities on platforms: when buyers have limited information, a seller's quality affects whether her buyers return to the platform, thereby impacting other sellers' future business. We propose an intuitive measure of this externality, applicable across a range of platforms. Guest Return […]
This three-day workshop will take place at Harvard University on March 18-20, 2019 in Science Center room 507. The main topic will be stability conditions in homological mirror symmetry. This workshop is funded by the Simons Collaboration in Homological Mirror Symmetry. Organizers: Denis Auroux, Yu-Wei Fan, Hansol Hong, Siu-Cheong Lau, Bong Lian, Shing-Tung Yau, Jingyu Zhao Speakers: Dylan Allegretti […]
Speaker: Greg Galloway (University of Miami) Title: On the geometry and topology of initial data sets in General Relativity Abstract: A theme of long standing interest (to the speaker!) concerns the relationship between the topology of spacetime and the occurrence of singularities (causal geodesic incompleteness). Many results concerning this center around the notion of topological censorship, which […]
The Workshop on Fluid turbulence and Singularities of the Euler/ Navier Stokes equations will take place on March 13-15, 2019. This is the first of two workshop organized by Michael Brenner, Shmuel Rubinstein, and Tom Hou. The second, Machine Learning for Multiscale Model Reduction, will take place on March 27-29, 2019. Both workshops will be […]
Speaker: Philippe Sosoe (Cornell) Title: A sharp transition for Gibbs measures associated to the nonlinear Schrödinger equation Abstract: In 1987, Lebowitz, Rose and Speer (LRS) showed how to construct formally invariant measures for the nonlinear Schrödinger equation on the torus. This seminal contribution spurred a large amount of activity in the area of partial differential equations […]
Speaker: Ian Martin (LSE) Title: Sentiment and Speculation in a Market with Heterogeneous Beliefs Abstract: We present a dynamic model featuring risk-averse investors with heterogeneous beliefs. Individual investors have stable beliefs and risk aversion, but agents who were correct in hindsight become relatively wealthy; their beliefs are overrepresented in market sentiment, so “the market” is bullish following good news and […]
