A note on Huemer’s Claim to immortality
Principia: An International Journal of Epistemology, 2020 According to Huemer (2019), existence is evidence of immortality, provided past time is infinite. The argument is based on, inter alia, an alleged contradiction between the fact of one’s existence now and its improbability.

Existence and non-existence of minimal graphs
Journal de Mathématiques Pures et Appliquées, 2023 We study the Dirichlet problem for minimal surface systems in arbitrary dimension and codimension via mean curvature flow, and obtain the existence of minimal graphs over arbitrary mean convex bounded $C^2$ domains for a large class of prescribed boundary data.

Mathematical Modelling and Analysis, 2015 In this paper, we discuss the existence of solutions for nonlinear qdifference equations with nonlocal q-integral boundary conditions. The first part of the paper deals with some existence and uniqueness results obtained by means of standard tools of ...

Existence and Non-existence of Half-Geodesics on $S^2$ [PDF]
, 2015 In this paper we study half-geodesics, those closed geodesics that minimize on any subinterval of length $l(\gamma)/2$. For each nonnegative integer $n$, we construct Riemannian manifolds diffeomorphic to $S^2$ admitting exactly $n$ half-geodesics ...

Existence of moduli spaces for algebraic stacks [PDF]
Inventiones Mathematicae, 2018 We provide necessary and sufficient conditions for when an algebraic stack admits a good moduli space and prove a semistable reduction theorem for points of algebraic stacks equipped with a Θ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage ...
