Title: Higher spin Killing spinors on 3-dimensional manifolds
Abstract: Killing spinors are special sections of the spinor bundle on spin manifolds. In standard spin geometry, we consider spin-1/2 spinor fields. In this talk, we define a higher-spin (spin-3/2, spin-5/2, ...) version of Killing spinors and study them in detail in dimension three. We also give explicit expressions of higher-spin Killing spinors on the 3-sphere and the hyperbolic 3-space. This is joint work with Yasushi Homma and Soma Ohno.

Title: Mabuchi solitons and Mabuchi constants on Fano admissible manifolds
Abstract: We study the existence of Mabuchi solitons on admissible manifolds as defined by Apostolov--Calderbank--Gauduchon--Tønnesen-Friedman. We prove that a Fano admissible manifold admits a Mabuchi soliton if and only if the Mabuchi constant is less than 1. We also provide an explicit formula for the Mabuchi constant on Fano admissible manifolds, which generalizes that of Mabuchi. Using this formula, we completely determine the existence and non-existence of Mabuchi solitons on Fano admissible manifolds over the complex projective space.
