Futaki invariants and harmonic metrics for the Hull-Strominger system

Abstract The Hull-Strominger system has been proposed as a geometrization tool for understanding the moduli space of Calabi-Yau threefolds with topology change (‘Reid’s Fantasy’). In this talk w...

Classification of metric fibration

Abstract In this talk, we explain the classificatin of the metric fibration that is a metric analogue of topological fibration introduced by T. Leinster in the study of magnitude. The magnitude

Loop-gas formulation of two-dimensional integrable models

Abstract I will formulate the finite-volume thermodynamics of a massive integrable QFT in terms of a has of relativistic loops. The loops interact through scattering factors associated with thei

Navigating the space of surfaces

Speaker Intro I was born in Wuhan and grew up in the little but quite famous German town Göttingen. I studied Economics at the FU Berlin and Mathematics at TU Berlin from 2003-2008 and obtained my

Elements of non-commutative algebraic geometry

Introduction The classical theory of algebraic geometry connects geometric concepts with corresponding notions in commutative algebra. In the recent decades there was an interest in building

Grothendieck lines in 3d SQCD and Quantum K-theory of the Grassmannian

Abstract In this talk I will revisit the correspondence between 3d $\mathcal{N}=2$ SQCD and the quantum K-theory of the Grassmannian variety Gr$(N_c, n_f)$. 3d $N=2$ SQCD has gauge group $U(N_c)_{k

Introduction to Spin(7) geometry

Introduction The classification of Riemannian manifolds with special holonomy contains two “exceptional” cases: G2 and Spin(7). Manifolds with holonomy contained in G2 or Spin(7) are called
