On the shape of the K-semistable domain and wall crossing for
K-stability
February 26, 2023
Mathematics
Algebraic Geometry
Fixing two positive integers d and k, a positive number v, and a
positive integer I, we prove that the K-semistable domain of the log pair
(X,∑j=1kDj) is a rational polytope lying in the k-dimensional
simplex $\overline...
Isoperimetric conditions, lower semicontinuity, and existence results
for perimeter functionals with measure data
February 26, 2023
Mathematics
Analysis of PDEs
We establish lower semicontinuity results for perimeter functionals with
measure data on Rn and deduce the existence of minimizers to these
functionals with Dirichlet boundary conditions, obstacles, or
volume-constraints. In oth...

Starting from a stochastic individual-based description of an SIS epidemic
spreading on a random network, we study the dynamics when the size n of the
network tends to infinity. We recover in the limit an infinite-dimensional
integro-diff...
Experimental Results on Potential Markov Partitions for Wang Shifts

Mathematics
Dynamical Systems
In this article we discuss potential Markov partitions for three different
Wang tile protosets. The first partition is for the order-24 aperiodic Wang
tile protoset that was recently shown in the Ph.D. thesis of H. Jang to encode
all tiling...

We introduce two new classes of covering codes in graphs for every positive
integer r. These new codes are called local r-identifying and local
r-locating-dominating codes and they are derived from r-identifying and
r-locating-dom...
Gravitational waves from first-order phase transition in an
electroweakly interacting vector dark matter model

Physics
High Energy Physics - Phenomenology
We discuss gravitational waves in an electroweakly interacting vector dark
matter model. In the model, the electroweak gauge symmetry is extended to
SU(2)0× SU(2)1×SU(2)2× U(1)Y and spontaneously
broken into SU...

Punctuation restoration plays an essential role in the post-processing
procedure of automatic speech recognition, but model efficiency is a key
requirement for this task. To that end, we present EfficientPunct, an ensemble
method with a mul...
