In this setting\, there are n spots on a one-way street and m cars attempting to park in those spots\, and 1≤m≤n. We let α= (a1\,a2\,…\,am) in [n]^m denote the parking preferences for the cars\, which enter the street sequentially. Car i drives to their preference a_i and parks there if the spot is available. Otherwise\, car i checks up to k spots behind their preference\, parking in the first available spot it encounters if any. If no spots are available\, or the car reaches the start of the street\, then the car returns to its preference and attempts to park in the first spot it encounters among spots a_i+1\,a_i+2\,…\,a_i+l. If car i fails to park\, then parking ceases. If all cars are able to park given the preferences in α\, then α is called a (k\,l)-pullback (m\,n)-parking function. Our main result establishes counts for these parking functions via a recursive formula.

Ideally\, probabilistic hazard assessments combine available knowledge about physical mechanisms of the hazard\, data on past hazards\, and any available precursor information. Systematically assessing the probability of rare\, yet catastrophic hazards adds a layer of difficulty due to limited observational data. Via computer models\, one can exercise potentially dangerous scenarios that may not have happened in the past but are probabilistically consistent with the aleatoric nature of previous geophysical behavior in the record. \nI will discuss recent work and ongoing methodological challenges toward making efficient and flexible geophysical hazard maps focusing on applications to volcanic flows (pyroclastic density currents) and post-fire debris flows.

He will discuss how modern agentic systems are being implemented across industry applications\, highlighting opportunities for students in applied mathematics\, data science\, and computational fields. \nThis event is hosted by the SIAM Student Chapter\, 51 URL:/math/event/siam-student-chapter-kolin-konjura/ LOCATION:EMS Building\, EMS E495\, 3200 Cramer St\, Milwaukee\, WI\, 53211\, United States CATEGORIES:SIAM Student Chapter ORGANIZER;CN="The Department of Mathematical Sciences":MAILTO:math-staff@uwm.edu X-TRIBE-STATUS: END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Chicago:20260313T140000 DTEND;TZID=America/Chicago:20260313T150000 DTSTAMP:20260417T071401 CREATED:20260303T000445Z LAST-MODIFIED:20260303T000445Z UID:10016270-1773410400-1773414000@uwm.edu SUMMARY:Colloquium: Dr. Jennifer Elder DESCRIPTION:Doing Anything You Want With Combinatorics\nDr. Jennifer Elder\nAssistant Professor of Mathematics\nMissouri Western State University \nWhen Mathematical Reviews first launched as a journal in 1940\, combinatorics was not listed as a research area. The Seven Bridges of Königsberg was solved in 1736\, so this absence is not due to later development of the field. Combinatorics has simply been hard to define on its own\, given that it is used as a tool in so many different areas of mathematics. \nThis talk will take the opposite point of view. We will center our focus on several research problems motivated from a combinatorial standpoint\, and the connections to other fields of research. These connections can be simple\, such as bridging different subareas of combinatorics: a study of a specific set of words uncovering unexpected properties of intervals in a lattice. Or the connections can be more odd\, connecting widely different areas of mathematics: a study of braid diagrams on k strands as a dynamical algebraic system.

In doing so\, we’ll prove a remarkable theorem about the way that SU(2) and SO(3) relate using quaternions and then discuss some connections to complex analysis at the end. In doing so\, we’ll take a very fun and (in my opinion) mind-blowing journey through spheres of different dimensions. Absolutely no knowledge of Lie theory is expected and I’ll be happy to clarify any details from topology or group theory that come up that you aren’t familiar with.

We then delve into understanding when the cusp space for a relatively hyperbolic group can be quasi-isometric to a hyperbolic group. For example\, real hyperbolic spaces admit uniform and non-uniform lattices. We show that this is the exception. In particular\, if a hyperbolic group is quasi-isometric to a cusped space for a relatively hyperbolic group\, then both groups are lattices acting on a rank-1 symmetric space. \nThis is joint work with Daniel Groves\, Emily Stark\, and Kevin Whyte.

One source of patterns that mathematicians have been exploring comes from juggling (the tossing of objects\, usually balls or clubs). We will look at multiple ways to describe juggling patterns that allow us to find new juggling patterns\, and to count how many possible patterns exist. We can compare answers to various problems to give a combinatorial proof of Worpitzky’s identity. We will also look at a few juggling-based problems that mathematics has not yet succeeded in answering. \nThis event is a part of the Marden Lecture Series\, each Spring the Department of Mathematical Sciences invites a distinguished mathematician to lecture to a general audience. The Marden Lecture honors Morris Marden (1905 – 1991)\, who founded our graduate program and made our department a research department. The Marden lecture is funded through the Miriam and Morris Marden Fund and is co-sponsored by the Department of Mathematical Sciences. \nA banquet will be held in the LEC AmFam Dream Studio following the lecture.

Have an activity/idea to share? Bring it with!!! \nWhat is the Community of Practice? \nThe Community of Practice is a space for everyone in the department (lecturers\, GTAs\, faculty) to come together and have chats\, professional development\, speakers\, workshops\, and more related to teaching and learning. There’s no sign-up; simply attend if you want! If you would like to be involved in any planning or would like to run a session\, please email me (henathan@uwm.edu) and let me know. \nThe Community of Practice Canvas Site \nWe have a Community of Practice Canvas site where we keep a signup and modules for past sessions.

A graph’s structure can efficiently stored in an array format. We can go one step further and replace arrays by matrices (which are arrays with benefits!)\, the eigenvalues of these matrices tell us some information about the graph. The extent to which we can understand the structure of the graph from these eigenvalues is spectral graph theory. We will do a quick walk through of some of the flavors of matrices that are studied in spectral graph theory\, and some results that arise from their study.

In this talk\, I present findings on how calculus students experience their interactions with instructors. Drawing on a qualitative study framed by academic validation and invalidation\, Black and Hispanic students share perspectives on their classroom experiences. They highlight instructional practices that support their learning\, including collaborative environments\, clear conceptual guidance\, availability outside of class\, and actions that make them feel valued. They also point to interactions that leave them feeling unsupported or not validated. Across these experiences\, students emphasize the importance of compassion\, care\, and instructor presence. By centering student voices\, this talk shows how faculty–student interactions shape students’ experiences in calculus beyond content delivery.
