Title: Are black holes and particles the same thing?

Abstract: I'll discuss the similarities between fundamental particles, thermal systems and black holes. We will play some quantitative games to see exactly how black holes are different from particles in the real world.

Having paid the real world our respects, we will talk about how black holes and fundamental particles *are* the same in string theory - a story rarely covered in popular propaganda, but central to the second superstring revolution. Funny enough, it allows for the "discovery" of new particles through writing down new black hole solutions.

I will then advertise my current work, in which I'm doing exactly that for string theory's wonky cousin, Higher-Spin Gravity.

Part I Title : Discrete geometric analysis and its application Abstract: Discrete geometric analysis is an attempt to discretize geometric analysis. Mathematics is often said “a common language of science”. As our world consists of atoms, which we consider as discrete objects, developing language to describe discrete objects, their geometric structures in particular, is important. I would like to discuss our challenge to establish discrete geometric analysis and its application to other science.

Speaker: Professor Changyu Guo , Shangdong University Title : Conservation law for harmonic mappings in higher dimensions Abstract :

It has been a longstanding open problem to find a direct conservation law for harmonic mappings into manifolds. In the late 1980s, Chen and Shatah independently found a conservation law for weakly harmonic maps into spheres, which can be interpreted by Noether's theorem. This leads to Helein's celebrated regularity theorem on weakly harmonic maps from surfaces. For general target manifolds, Riviere discovered a direct conservation law in two dimension in 2007, allowing him to solve two well known conjectures of Hildebrandt and Heinz. As observed by Riviere-Struwe in 2008, due to lack of Wente's lemma, Riviere's approach does not extend to higher dimensions. In a recent joint work with Chang-Lin Xiang, we successfully found a conservation law, in the spirit of Riviere, for a class of weakly harmonic maps (around regular points) into general closed manifolds in higher dimensions.

Title: Behavioral, Social, and Institutional Dimensions of Cooperation

Abstract: Common goods are at the heart of many challenges facing humankind. Protective measures – such as mitigating climate change or not overexploiting natural resources – are collectively beneficial, yet costly to individual stakeholders with diverse interests. Common goods may thus be jeopardized by selfish agents at all levels – be they collaborators, citizens, companies, cities, or countries – resulting in social dilemmas that often follow a pattern known as the ‘tragedy of the commons.’ Salient examples concern not only climate change and natural resources, but also clean air, civil security, social welfare, ecosystem services, land use, prudent urbanization, natural-disaster protection, demographic planning, and the functioning of the internet. In this presentation, I will illustrate how quantitative analyses can help address the behavioral, social, and institutional dimensions of these challenges, promoting cooperative collective actions and the safeguarding of common goods.

Title: The level-set mean curvature flow equation versus the total variation flow equation

Abstract: The level-set mean curvature flow equation has been introduced to track an evolving hypersurface by its mean curvature after it develops singularities. A level-set of a solution of the level-set mean curvature flow equation moves its mean curvature. The total variation flow equation is often used to remove noise from images. Although these two equations look similar, analytic properties are quite different; the former equation is a local equation while the latter is a nonlocal equation. In this talk, we compare these two equations as well as a few applications.
