SUMMARY:Workshop / Seminar:GLNT: Higher p-adic modular forms\; Frobenius lifting and a geometric theory of companion forms
DESCRIPTION:George Boxer's talk:\nTitle: Higher p-adic modular forms\n\nAbstract: The goal of the theory of higher p-adic modular forms is to study the p-adic properties of higher coherent cohomology of Shimura varieties\, just as usual p-adic modular forms are used to study classical modular forms (or coherent H^0).  In this talk I will try to motivate why we should study higher coherent cohomology of Shimura varieties and then give an introduction to higher p-adic modular forms and in particular some generalizations of the works of Hida and Coleman on classicality and families.  All this is joint with Vincent Pilloni.\n\nVincent Pilloni's talk:\nTitle : Frobenius lifting and a geometric theory of companion forms\n\nAbstract : We describe the obstruction to lift Frobenius on Siegel Shimura varieties modulo p^2. We give an application to the theory of companion forms on the modular curve (originally due to Gross\, Coleman-Voloch\, Faltings-Jordan) and on Siegel threefolds.

SUMMARY:Workshop / Seminar:Particle Systems with Local Interactions via Hitting Times and Cascades on Graphs
DESCRIPTION:We study particle systems interacting via hitting times on sparsely connected graphs\, following the framework of Lacker\, Ramanan and Wu (2023). We provide general robustness conditions that guarantee the well-posedness of physical solutions to the dynamics\, and demonstrate their connections to the dynamic percolation theory. We then study the limiting behavior of the particle systems\, establishing the continuous dependence of the joint law of the physical solution on the underlying graph structure with respect to local convergence and showing the convergence of the global empirical measure\, which extends the general results by Lacker et al. to systems with singular interaction. The model proposed provides a general framework for analyzing systemic risks in large sparsely connected financial networks with a focus on local interactions\, featuring instantaneous default cascades. This work is done jointly with Qinxin Yan.

SUMMARY:Workshop / Seminar:Quadratically Regularized Optimal Transport
DESCRIPTION:The quadratically regularized optimal transport problem (QOT) has emerged in the literature as a sparse alternative to the celebrated entropically regularized transport problem (EOT). Unlike EOT\, whose solutions always have full support—even for small regularization parameters—QOT solutions\, or QOT plans\, tend to approximate the support of the unregularized transport problem\, which concentrates on the graph of a function under mild conditions. This gives way to some natural questions that I will intend to answer in this talk\, such as: Why do we care about sparsity? How does this sparsity manifest\, and is it monotone? Can we efficiently approximate QOT? This is joint work with my co-advisor Marcel Nutz and Dr. Alberto González-Sanz.

SUMMARY:Well-being:Virtual Dialectical Behavior Therapy (DBT) Group for Adults
DESCRIPTION:Are you looking to gain better control of your thoughts and emotions? Our Psychological Clinic invites adults 18 and older to participate in our weekly Dialectical Behavior Therapy (DBT) group sessions\, held virtually for your convenience. Learn practical skills for managing anxiety\, depression\, and challenging situations with the support of experienced clinicians and peers.\n\nWhy Choose DBT Group Therapy?\nGroup sessions offer unique benefits\, including opportunities to learn new techniques\, share experiences\, and build supportive connections. You’ll develop practical skills in mindfulness\, emotion regulation\, interpersonal effectiveness\, and distress tolerance—essential tools for managing strong emotions and handling stress. Research shows that connecting with peers in a supportive group environment encourages real-world growth\, accountability\, and lasting change.\n\nProgram Details:\n- Who: Adults 18+ interested in building coping skills\, managing emotions\, and improving relationships.\n- When: Tuesdays from 5:00 – 6:30 p.m. (via Zoom).\n- Structure: The program runs in ongoing 4-month cycles\, each focusing on a different theme.\n- Flexible Start: New participants can join at the first Tuesday session of any month.\n- Cost: $45 per session (insurance may help cover costs).
