Writing a journal article can be a daunting task, characterized by frustration instead of progress. This four-part workshop series will breakdown the task of writing an empirical journal article into manageable pieces so that you can move your project forward. Led by WCC lecturer Adrienne Tierney, Ed.D, we will discuss how to approach each section and how to use writing as a problem-solving tool in creating a meaningful paper that conveys your research clearly and effectively. We encourage you to attend all sessions of the series, but you are also welcome to sign up for separate sessions.Part 1. Getting Started: Creating a Plan and Drafting an IntroductionTuesday, February 11th, 4:00-5:30pmPart 2. Getting to the Data: Methods and ResultsTuesday, February 18th, 4:00-5:30pmPart 3. Interpreting Your Findings: DiscussionTuesday, February 25th, 4:00-5:30pmPart 4. From Paper to Publication: Revision and SubmissionTuesday, March 4th, 4:00-5:30pm

Speaker: Alex Lubotzky (Weizmann Institute & the Hebrew University, Simons Distinguished Visiting Professor, MIT)Title: High Dimensional Expanders (HDX) and their applications in pure math and computer scienceAbstract:Expander graphs have been an intensive topic of research in math and CS during the last six decades. In the last two decades a high dimensional theory has emerged with (very different) applications in math & CS.In this series of 8 independent (but related) lectures we present some aspects of the theory of HDX and its applications, a number of open problems and suggestions for further research.A more detailed plan:1. Thursday 2/20/25, 4:30pm, 2-190 (Math Colloquium); refreshments served at 4pm in 2-290  Introduction: three main problems(a) Gromov overlapping property(b) Locally testable codes(c) Are all groups sofic?2. Tuesday 2/25/25, 4:15-5:15pm, 32-G449 (Theory of Computing Colloquium), refreshments served at 4pmGood Locally testable codes3. Wednesday 2/26/25, 9:30-11am, 2-449Expander graphs: combinatorics, spectral gap, representation theory(Kazhdan property (T), property (\tau) and more) and property testing4. Wednesday 3/5/25, 9:30-11am, 2-449Geometric & topological expanders, Coboundary expanders, Random simplicial complexes and Property testing5. Wednesday 3/12/25, 9:30-11am, 2-449From Ramanujan graphs to Ramanujan complexes6. Wednesday 3/19/25, 9:30-11am, 2-449Stability and group approximation, Garland Theorem and the p-adic Deligne central extensionsWednesday 3/26/25 - Spring vacation7. Wednesday 4/2/26, 9:30-11am, 2-449Some more CS: Agreement tests, direct product test; PCP8. Wednesday 4/9/25, 9:30-11am, 2-449Are there non-sofic groups? The Aldous-Lyons conjecture and more

Speaker: Tonghai Yang (University of Wisconsin, Madison)Title: (A)FL at infinity and arithmetic generating series of CM cyclesAbstract:In this talk, we propose a FL and AFL at the real place with a proof of FL (if time permits). We also define a generating series of arithmetic CM cycles indexed by integer and conjecture it to be modular. Finally, we explain the connection between the two. This is a preliminary report of my joint work with Andreas Mihatsch and Siddarth Sankaran.

Disabled@MIT is hosting a movie night! My Beautiful Stutter follows five kids who stutter, ages 9 to 18, from all over the United States and all walks of life, who, after experiencing a lifetime of bullying and stigmatization, meet other children who stutter at an interactive arts-based program, The Stuttering Association for the Young, based in New York City. (https://www.mybeautifulstutter.com/) The movie is 90 minutes and we'll have snacks and some time for socializing and discussion afterwards. All are welcome -- you don't need to be a member of our group, a student, or have a disability to come. Date: Tuesday, February 25th, 2025Time: 4:30 - 6:30 pmLocation: MIT Building 33, room 33-218RSVP: https://forms.gle/VsQhB7uCtrieqvDr7 Accessibility: We'll be hosting this event indoors in a wheelchair accessible room. Mask-wearing is requested and high-quality masks will be provided. Please let us know in this form if you have any other access needs!
