Analysis of modified Holling-Tanner model with strong Allee effect
Mathematical Biosciences and Engineering, 2023 In this paper, we study a predator-prey system, the modified Holling-Tanner model with strong Allee effect. The existence and stability of the non-negative equilibria are discussed first.

Recognition and Implementation of Contact Simple Map Germs from (ℂ2, 0) → (ℂ2, 0)
Mathematics, 2023 The classification of contact simple map germs from (C2,0)→(C2,0) was given by Dimca and Gibson. In this article, we give a useful criteria to recognize this classification of contact simple map germs of holomorphic mappings with finite codimension.

Island on codimension-two branes in AdS/dCFT
Journal of High Energy Physics, 2022 The previous studies of the island and double holography mainly focus on codimension-one branes. This paper explores the island on the codimension-two brane in AdS/dCFT.

Codimension one distributions and stable rank 2 reflexive sheaves on threefolds
Anais da Academia Brasileira de Ciências, 2021 % We show that codimension one distributions with at most isolated singularities on certain smooth projective threefolds with Picard rank one have stable tangent sheaves.

Codimension-2 defects and higher symmetries in (3+1)D topological phases
SciPost Physics, 2023 (3+1)D topological phases of matter can host a broad class of non-trivial topological defects of codimension-1, 2, and 3, of which the well-known point charges and flux loops are special cases.

Equilibria and Bogdanov-Takens Bifurcation Analysis in the Bazykin’s Predator-Prey System
Discrete Dynamics in Nature and Society, 2022 In the paper, we proposed a Bazykin’s predator-prey system to explore the equilibrium point and Bogdanov-Takens bifurcation problems. Firstly, we derived some key parameter threshold conditions to ensure that the Bazykin’s predator-prey system had a ...

A shorter path to celestial currents
Journal of High Energy Physics, 2023 Here we consider what happens when we lift a codimension-1 slice of the celestial sphere to a codimension-1 slice of the bulk spacetime in a manner that respects our ability to quotient by the null generators of I ± to get to our codimension-2 hologram ...

On Delaunay’s Theorem Classifying Coincidences of Parallelohedra at Faces of Codimension 3
Моделирование и анализ информационных систем, 2013 In 1929 B.N. Delaunay obtained the complete classification of all possible combinatorial coincidence types of parallelohedra at their faces of codimension 3.

Journal of High Energy Physics, 2023 We expand on our results in [1] to present a broad new class of gravitational observables in asymptotically Anti-de Sitter space living on general codimension-zero regions of the bulk spacetime.

Interpolating between multi-center microstate geometries
Journal of High Energy Physics, 2021 We study interpolation between two multi-center microstate geometries in 4d/5d that represent Lunin-Mathur geometries with circular profiles. The interpolating solution is a Lunin-Mathur geometry with a helical profile, and is represented by a 2-center ...
