Title: Arithmetic Electric-Magnetic Duality
Abstract: The Langlands program is a grand organizing vision for a large slice of number theory and representation theory. A shockingly accurate metaphor for the Langlands program has emerged as electric-magnetic duality in four-dimensional gauge theory, but where the role of spacetime is played by objects from arithmetic. I will discuss this general picture and begin to describe recent work with Yiannis Sakellaridis and Akshay Venkatesh, in which we apply ideas from QFT (the Gaiotto-Witten electric-magnetic duality for boundary theories) to a fundamental problem in number theory, predicting the relation between L-functions of Galois representations and integrals of automorphic forms.

Special Seminar by David Ben Zvi
Time: 1:00 PM - 2:00 PM
Location: 313
Title: Fixed points, traces and characters
Abstract: This talk will explore one of my favorite themes in mathematics: the abstract notion of a trace and its manifestation via fixed points in geometry and partition functions in quantum mechanics. This relation gives rise to a sequence of increasingly sophisticated character formulas, as well as a broader sense of what characters are. I will conclude with a perspective on L-functions of Galois representations as characters, developed in my joint work with Yiannis Sakellaridis and Akshay Venkatesh. (The talk is meant to be independent of the previous day's talk but with a closely related end-point.)

Title: An Exceptional Approach to Kaluza-Klein Spectroscopy
Abstract: The spectrum of light single-trace operators of holographic CFTs at strong coupling and large N, can be mapped to the spectrum of Kaluza-Klein (KK) excitations over the dual AdS supergravity solutions. Computing these KK spectra is usually a difficult task even for the simplest AdS solutions. In this talk, I will review new spectral methods based on Exceptional Field Theory, a duality-covariant reformulation of the higher-dimensional supergravities. For certain AdS/CFT dual pairs, these methods bypass the difficulties and reduce the KK spectral problem to simple diagonalisation of suitable mass matrices. I will illustrate these methods for the class of AdS4 solutions of M-theory and type II string theory that uplift consistently from D=4 maximal gauged supergravities. Also, I will describe progress to extend these methods to AdS solutions that uplift from half-maximal supergravities.

Math Event: Algebraic Geometry Seminar: Svetlana Makarova - Higher Fano manifolds
Time: 4:00 PM - 5:00 PM
Location: Math P-131
Title: Higher Fano manifolds
Speaker: Svetlana Makarova [Australian National University]
Abstract: Fano manifolds are projective manifolds whose anticanonical class (determinant of the tangent bundle) is ample. The positivity condition has far-reaching geometric implications, e.g., a Fano manifold over complex numbers is simply connected, which has an analogue on the algebro-geometric side: any Fano manifold is covered by rational curves, and in fact rationally connected, i.e., there are rational curves connecting any two of its points. In a series of papers, De Jong and Starr introduce and investigate possible candidates for the notion of higher rationally connectedness, inspired by the natural analogue in topology, and define that a projective manifold X is 2-Fano if it is Fano and the second Chern character ch2(T_X) is positive (intersects positively with every surface in X). In a similar way, one defines n-Fano manifolds for any n ≥ 2; for instance, P^n is n-Fano. In this talk, I will give evidence for the analogy with higher connectedness and present certain classification results. In the second half of the talk, I will focus on the recent progress towards proving the conjecture that the only toric higher Fano manifolds are projective spaces. View Details

Title: New Channels & Objects at the LHC
Abstract: The LHC is such a successful experimental program that we not only discovered the Higgs boson, but the experimental colleagues have been continuously running numerous powerful searches for new physics with it. It seems to be in an auto-piloting mode (for the theorists) that our job becomes improving the SM precision predictions, sometimes with machine learning, and waiting to interpret new results. I hope to show in this talk that there are still new meaningful channels and objects we can propose to study. I will show two examples from my ongoing work. The first is a new search for the SM exotic decay of the W boson, which can also be used to look for new particles. In the second part, I will show how adding the precision timing information available at HL-LHC brings in new capabilities and generates new theoretical questions, allowing us to construct new objects in the SM and BSM.
