Pluriclosed Flow and Hermitian-Symplectic Structures
We observe that pluriclosed flow preserves Hermitian-symplectic structures. And we extend pluriclosed flow to a flow of Hermitian-symplectic forms by...

Feature Engineering with Regularity Structures
We investigate the use of models from the theory of regularity structures as features in machine learning tasks. A model is a polynomial function of...

Model structures on finite total orders
We initiate the study of model structures on (categories induced by) lattice posets, a subject we dub homotopical combinatorics . In the case of a...

Fabricating Porous Structures using Robotic Hotwire Cutting
With an increasing interest in fabricating complex structures in architectural design, the concept of porosity has become a vital topic, opening up...

On a Problem of Conrad on Riesz Space Structures
This paper is concerned with Riesz space structures on a lattice ordered abelian group, continuing a line of research conducted by the author and the...

Vacuum Structures Revisited
We consider the relationship between the higher symmetry and the dynamical decomposition in supersymmetric gauge theory in various dimensions by...

Aggregation Tree Construction Using Hierarchical Structures
In the problem under consideration it is necessary to find a schedule of conflict-free data aggregation of a minimum length, i.e. to determine the...

Minimal Triangular Structures on Abelian Extensions
We study minimal triangular structures on abelian extensions. In particular, we construct a family of minimal triangular semisimple Hopf algebras and...

Generalized Sasakian structures from a Poisson geometry viewpoint
In this paper we define a canonical Poisson structure on a normal generalized contact metric space and use this structure to define a generalized...

p-Kähler and balanced structures on nilmanifolds with nilpotent complex structures
Let ( X , J ) be a nilmanifold with an invariant nilpotent complex structure. We study the existence of p -Kähler structures (which include Kähler and...

Testing high-dimensional covariance structures using double-normalized observations
In this paper, we focus on the test for high-dimensional covariance structures using double-normalized observations for an elliptical population. By...

Normal Crossings Singularities for Symplectic Topology: Structures
Our previous papers introduce topological notions of normal crossings symplectic divisor and variety, show that they are equivalent, in a suitable...

Reconnection of Infinitely Thin Antiparallel Vortices and Coherent Structures
One of the characteristic features of turbulent flows is the emergence of many vortices which interact, deform, and intersect, generating a chaotic...

Exact SDP relaxations for quadratic programs with bipartite graph structures
For nonconvex quadratically constrained quadratic programs (QCQPs), we first show that, under certain feasibility conditions, the standard...

Harmonic almost complex structures on almost abelian Lie groups and solvmanifolds
An almost abelian Lie group is a solvable Lie group with a codimension one normal abelian subgroup. We characterize almost Hermitian structures on...

Discontinuity Structures and Solitary Waves in Electromagnetic Hydrodynamics Associated with Linear and Nonlinear Alfvén Wave Resonances
AbstractNondissipative and weakly dissipative discontinuity structures are considered. A special numerical method for studying periodic waves is...

Passivity Techniques and Hamiltonian Structures in Discrete Time
The object of this paper is to show the impact of representing discrete-time dynamics as two coupled difference/differential equations in...

Gluing compactly generated t-structures over stalks of affine schemes
We show that compactly generated t-structures in the derived category of a commutative ring R are in a bijection with certain families of compactly...

Parametric Interlocking Elastic Wooden Plate Joint for Complex Structures
Interlocking wooden joints are a material driven traditional structural method that is used in complex wooden structures. Nowadays they are...
