The production, reception, and subsequent applications of Lee&#8217;s research clarify the aims of biometricians, the perceived legitimacy of arguments based on regression analysis (by those who did and did not understand the mathematics), and ways in which bias was measured and assessed.<\/div>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n<p><b>The USC Math Club<\/b><br \/>\n<em>24 Feb 2025<\/em><br \/>\n<b>Spencer Gerhardt (USC)<\/b><br \/>\n<em>Some Mathematical Background to Minimalism<\/em><\/p>\n<p>&nbsp;<\/p>\n<div style=\"margin-bottom:0.5cm;\">In this talk, we trace the development of musical minimalism in the early 1960s through its interactions with mathematicians and mathematical ideas.

Nonetheless, the idea of fractal symmetry in music seems much less common.  In this talk, I&#8217;ll describe recent research investigating the presence of fractal structures in Africanist music, in response to a hypothesis of choreographer Reggie Wilson. I&#8217;ll describe both the project and &#8220;scientific&#8221; findings, as well as the broader context of my unexpected and ongoing engagement with Reggie Wilson and his Fist and Heel Performance Group at the interplay of math and dance.  This is joint work with Claudio G\u00f3mez-Gonz\u00e1les, Sidhanth Raman and Siddharth Viswanath.<\/div>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n<p><b>Probability and Statistics Seminar<\/b><br \/>\n<em>17 Nov 2023<\/em><br \/>\n<b>Peter Kagey (Harvey Mudd College)\u00a0<\/b><br \/>\n<em>Expected value of letters of permutations with a given number of $k$-cycles<\/em><\/p>\n<p>&nbsp;<\/p>\n<div style=\"margin-bottom:0.5cm;\">The probability that a uniformly random permutation\u00a0on $2n$ letters has exactly $\\alpha$ transpositions is equal to the probability that a uniformly random isometry of the $n$-cube has exactly $\\alpha$ pairs of faces that are fixed. In this talk, I will describe generalizations of this relationship, show how this gives information about the expected value of letters of permutations with a given number of $k$-cycles, and propose several open questions related to families of permutation statistics.<\/div>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n<p><b>Math Education Seminar<\/b><br \/>\n<em>13 Nov 2023<\/em><br \/>\n<b>Philip Ording (Pratt Institute)\u00a0<\/b><br \/>\n<em>Geometry for Artists: Max Dehn at Black Mountain College<\/em><\/p>\n<p>&nbsp;<\/p>\n<div style=\"margin-bottom:0.5cm;\">This talk will present joint research with Brenda Danilowitz on Geometry for Artists, a workshop that Max Dehn developed in the late 1940s at Black Mountain College in North Carolina.

Models of Newtonian fluids in the real world often result in a system of dissipative equations. In particular, these equations have an internal diffusion term that allows them to dissipate energy, but the way in which this happens in general is non-trivial and chaotic; in a word, turbulent.\u00a0 As a result, for many of these systems one has exponential divergence of trajectories that start infinitesimally close to one another, making them highly unpredictable. As a result, the first challenge of many to accurately simulate turbulent flows we directly observe in the real world (like the climate) is that the initial state of our system trajectory is unknown, and guessing a good initial state has been a subject of intense study for decades. Data assimilation addresses this issue by continually incorporating observed data into the model equations. In this talk, I will discuss my work using a theoretically simple yet rigorous approach to data assimilation in order to accurately model fluid flows.<\/div>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":328,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-7549","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
