Twin-width of random graphs
Jungho Ahn, Debsoumya Chakraborti, Kevin Hendrey +2
We investigate the twin-width of the Erdős-Rényi random graph . We unveil a surprising behavior of this parameter by showing the existence of a constant su…
Crystal base of the negative half of the quantum superalgebra
Il-Seung Jang, Jae-Hoon Kwon, Akito Uruno
We construct a crystal base of , the negative half of the quantum superalgebra . We give a combinatorial description of the asso…
A unified Erdős-Pósa theorem for cycles in graphs labelled by multiple abelian groups
J. Pascal Gollin, Kevin Hendrey, O-joung Kwon +2
In 1965, Erdős and Pósa proved that there is an (approximate) duality between the maximum size of a packing of cycles and the minimum size of a vertex set hitting all cycles. Such…
Model-based cross-correlation search for gravitational waves from the low-mass X-ray binary Scorpius X-1 in LIGO O3 data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692
We present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run…
The proper conflict-free -coloring problem and the odd -coloring problem are NP-complete on bipartite graphs
Jungho Ahn, Seonghyuk Im, Sang-il Oum
A proper coloring of a graph is \emph{proper conflict-free} if every non-isolated vertex has a neighbor whose color is unique in the neighborhood of . A proper coloring of a…
Training Process of Unsupervised Learning Architecture for Gravity Spy Dataset
Yusuke Sakai, Yousuke Itoh, Piljong Jung +11
Transient noise appearing in the data from gravitational-wave detectors frequently causes problems, such as instability of the detectors and overlapping or mimicking gravitational-…
Rabinowitz Floer homology of negative line bundles and Floer Gysin sequence
Peter Albers, Jungsoo Kang
This article is concerned with the Rabinowitz Floer homology of negative line bundles. We construct a refined version of Rabinowitz Floer homology and study its properties. In part…
The Topology of the set of line Transversals
Otfried Cheong, Xavier Goaoc, Andreas F. Holmsen
We prove that for any set of pairwise disjoint open convex sets in , the connected components of the set of lines intersecting every member of are co…
Stability of monotone, non-negative, and compactly supported vorticities in the half cylinder and infinite perimeter growth for patches
Kyudong Choi, In-Jee Jeong, Deokwoo Lim
We consider the incompressible Euler equations in the half cylinder . In this domain, any vorticity which is independent of defines a statio…
A colorful Goodman-Pollack-Wenger theorem
Andreas F. Holmsen
Hadwiger's transversal theorem gives necessary and sufficient conditions for the existence of a line transversal to a family of pairwise disjoint convex sets in the plane. These co…
Search for continuous gravitational wave emission from the Milky Way center in O3 LIGO--Virgo data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1667
We present a directed search for continuous gravitational wave (CW) signals emitted by spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling e…
On a rainbow extremal problem for color-critical graphs
Debsoumya Chakraborti, Jaehoon Kim, Hyunwoo Lee +2
There has been extensive studies on the following question: given graphs over a common vertex set of size , what conditions on ensures a `colorful' co…
Identifying multichannel coherent couplings and causal relationships in gravitational wave detectors
Piljong Jung, Sang Hoon Oh, Young-Min Kim +4
The gravitational-wave detector is a complex and sensitive collection of advanced instruments that are impacted not only by mechanical/electronics systems but also by the surroundi…
The Wiener criterion for nonlocal Dirichlet problems
Minhyun Kim, Ki-Ahm Lee, Se-Chan Lee
We study the boundary behavior of solutions to the Dirichlet problems for integro-differential operators with order of differentiability and summability . We es…
Performance of the KAGRA detector during the first joint observation with GEO 600 (O3GK)
KAGRA Collaboration, H. Abe, R. X. Adhikari +212
KAGRA, the kilometer-scale underground gravitational-wave detector, is located at Kamioka, Japan. In April 2020, an astrophysics observation was performed at the KAGRA detector in…
Affinization of -oscillator representations of
Jae-Hoon Kwon, Sin-Myung Lee
We introduce a category of -oscillator representations of the quantum affine algebra . We show that $\widehat{\…
First joint observation by the underground gravitational-wave detector, KAGRA, with GEO600
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1669
We report the results of the first joint observation of the KAGRA detector with GEO600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser inter…
Independent domination of graphs with bounded maximum degree
Eun-Kyung Cho, Jinha Kim, Minki Kim +1
An independent dominating set of a graph, also known as a maximal independent set, is a set of pairwise non-adjacent vertices such that every vertex not in is adjacent to s…
Prime vertex-minors of a prime graph
Donggyu Kim, Sang-il Oum
A graph is prime if it does not admit a partition of its vertex set such that and the rank of the submatrix of its adjacency matrix is…
