Myers-Steenrod theorems for metric and singular Riemannian foliations
Diego Corro and Fernando Galaz-García
We prove that the group of isometries preserving a metric foliation on a closed Alexandrov space \(X\), or a singular Riemannian foliation on a…
Stability of the generalized Lagrangian mean curvature flow in cotangent bundle

In this paper, we consider the stability of the generalized Lagrangian mean curvature flow of graph case in the cotangent bundle, which is first…
Non-homogeneous fully nonlinear contracting flows of convex hypersurfaces
Pengfei Guan, Jiuzhou Huang, Jiawei Liu
We consider a general class of non-homogeneous contracting flows of convex hypersurfaces in \(\mathbb R^{n+1}\), and prove the existence and…
The twisted conical Kähler-Ricci solitons on Fano manifolds
Xishen Jin, Jiawei Liu
In this paper, we show the relation between the existence of twisted conical Kähler-Ricci solitons and the greatest log Bakry-Emery-Ricci lower bound…
Period functions for vector-valued Maass cusp forms of real weight, with an application to Jacobi Maass cusp forms
Roelof Bruggeman, YoungJu Choie, Anke Pohl
For vector-valued Maass cusp forms for SL(2,Z) with real weight k∈R and spectral parameter s∈C, Res∈(0,1), s≢±k/2 mod 1, we propose a notion of…
