QMAP colloquium

The QMAP colloquium is our main regular event. The aim is to bring high profile speakers to address audiences of both physicists and mathematicians interested in the core topics of the QMAP center. The organizers are Tudor Dimofte and Jaroslav Trnka; contact them for any questions.

Title: Black hole fusion made easy

Abstract: The fusion of two black holes --- a signature phenomenon of General Relativity --- is usually regarded as a process so complex that nothing short of a supercomputer simulation can accurately capture it. But this is not quite so – not always. I will explain how the event horizon of the fusion can be found in a very simple way when one of the black holes is much smaller than the other. The construction is not only simple but also accurate, general, and realistic: these fusions are occurring out there, all the time. Remarkably, the ideas and techniques involved are elementary, so the construction can be understood with only a basic knowledge of General Relativity.

Title: Spacetime, Quantum Mechanics and Positive Geometry

Time & Location: 10:30am (refreshment at 10:15am, reception after colloquium), Mathematical Science Building, room 1147.

Abstract: Spacetime and Quantum Mechanics form the pillars of our understanding of modern physics, but there are several indications that these concepts are approximate and must emerge from deeper principles, undoubtedly involving new mathematics. In this talk I will describe some emerging ideas along these lines, and present a new formulation of some very basic physics-- fundamental to particle scattering and to cosmology--not following from quantum evolution in space-time, but associated with simple new mathematical structures in "positive geometry". In these examples we can concretely see how the usual rules of space-time and quantum mechanics can arise, joined at the hip, from fundamentally geometric and combinatorial origins.
