Title: From Hilbert’s 16th Problem to Physics Speaker: Charles Nash (NUI Maynooth) Abstract: We shall describe a link between Hilbert’s sixteenth problem (part (i)) concerning real algebraic curves and condensed matter physics. The central result is some work of Kenyon and… Read More

Title: Quantum Correlations in Space & Time Speaker: Joe Fitzsimons (Singapore University of Technology and Design) Abstract: In ordinary, non-relativistic, quantum physics, time enters only as a parameter and not as an observable: a state of a physical system is specified… Read More

Title: Anomalous Transport Speaker: Karl Landsteiner (Universidad Autónoma de Madrid) Abstract: The concept of symmetry is one cornerstone of modern theoretical physics, quantum mechanics is another. Sometimes they are incompatible with each other. These incompatibilities are called anomalies. They constrain possible… Read More

Title: An Introduction to Causal Set Theory Speaker: Dionigi M.T. Benincasa (DIAS) Abstract: Causal set theory is a sum-over-histories approach to quantum gravity, where the histories are discrete spacetimes (called causal sets) defined as locally finite partial orders. Causal sets were… Read More

Title: A Hopf algebra for Feynman diagrams and integral Speaker: Ruth Britto (Trinity College Dublin) Abstract: I will present a combinatorial operation on one-loop Feynman diagrams, described by cutting and pinching edges, that corresponds to the Hopf-algebraic coaction on the… Read More
