For each dg operad P, I will present a homotopically-coherent version of "P-ideal". This presentation extends without change to a many-to-many generalization of operads with tree-level compositions called "dioperads". Whereas operads describe algebras, dioperads describe bialgebras, and "P-ideals" for a dioperad P are simultaneously ideals and coideals. In the case where P describes Frobenius...   More >

This paper seeks to read Liang Chenyu’s dramatic masterpiece, Washing Gauze (Huansha ji), with reference to the rise of courtesans as “theater women” and the subsequent changes in the performance culture in the late sixteenth century. It argues that the play explodes the literary tradition to which it belong by staging female chorus, dance forms and their training sessions, and outdoors music...   More >

In this talk I will emphasize applications of model theory...   More >

The Effect of Cumulative Advantages on the Stability and Dynamics of Collaborations in US Physics, Chemistry and Sociology from 1980 to 2015

 Oliver Wieczorek, Visiting Scholar, Sociology, Bamberg, Germany; Heiko Heiberger, Postdoctoral Researcher,Department for Micro-Sociology at University of Bremen, Germany

 Center for Studies in Higher Education

In academia, effects of “cumulative advantage” are well studied in regards to different types of resources. Those resources are money, influence, number of collaborations, number of publications and the impact of the findings. In other words: the rich and famous departments and researchers get richer and more famous over time while the poor get (relatively) poorer. This effect is visible on both...   More >

Combinatorics Seminar: Dyck paths and positroids from unit interval orders

Seminar | January 30 | 12:10-1 p.m. | 939 Evans Hall

 Anastasia Chavez and Felix Gotti, UC Berkeley

 Department of Mathematics

It is well known that the number of non-isomorphic unit interval orders on $[n]$ equals the $n$-th Catalan number. Using work of Skandera and Reed and work of Postnikov, we show that each unit interval order on $[n]$ naturally induces a rank $n$ positroid on $[2n]$. We call the positroids produced in this fashion unit interval positroids. We characterize the unit interval positroids by describing...   More >

Single-molecule experiments investigate the kinetics of individual molecules and thus can substantially enhance our understandings of various organisms. Analyzing data from single-molecule experiments poses a number of challenges: (a) the inherent stochasticity of molecules is usually buried in random experimental noise; (b) single-molecule behavior can be highly volatile. For both of these...   More >
