[Title] Minimal Surfaces in Riemann-Cartan Geometry
[Discipline] Differential Geometry
[Abstract]
In this talk, we extend the classical theory of minimal surfaces studied in Euclidean and Riemannian geometry to a more general framework in Weitzenböck and Riemann-Cartan geometry, which incorporates torsion. After providing a gentle introduction to minimal surface theory, we present theorems that generalize classical results concerning the holomorphic nature of the Hopf differential, the conformality of the Gauss map, and the minimality of surfaces.

[Title] The pluripotential complex Monge-Ampère flows
[Discipline] PDE, Differential Geometry
[Abstract]
The Kahler-Ricci flow has been a main interest in the field of Kahler geometry, for its application to the construction of canonical metrics. It is a classical result that solving a Kahler-Ricci flow is equivalent to solving a parabolic PDE named complex Monge-Ampere flow. Recently, Guedj-Lu-Zeriahi (‘2021) introduced a parabolic pluripotential theory and studied the weak solutions of degenerate complex Monge-Ampere flows. In this talk, I will first explain their approach with the classical results in elliptic pluripotential theory. I will also explain my recent result on the existence and uniqueness of the solution for more general measures, which is a generalization of the result by Guedj-Lu-Zeriahi.

[Title] Toward an induced grid minor theorem
[Discipline] Combinatorics
[Abstract]
The Grid Minor Theorem by Robertson and Seymour is one of the most important results in structural graph theory. In recent years, there has been growing interest in exploring an induced analogue of this theorem. In this talk, we prove that for all positive integers $k$ and $d$, the class of $K_{1,d}$-free graphs not containing the $k$-ladder or the $k$-wheel as an induced minor has a bounded tree-independence number. These two graphs can be considered as strong evidence for existence of a grid as an induced minor. Our proof uses a generalization of the concept of brambles for tree-independence number. This is based on joint work with Claire Hilaire, Martin Milanič, and Sebastian Wiederrecht.
