Embeddings into countably compact Hausdorff spaces

open access: yesUkrains’kyi Matematychnyi Zhurnal, 2023
UDC 515.122 We consider the problem of characterization of topological spaces  embedded into countably compact Hausdorff topological spaces. We study the separation axioms for subspaces of Hausdorff countably compact topological spaces and construct an example of a regular separable scattered topological space that cannot be embedded into a Urysohn ...

A Generic Embedding Class-I Model via Karmarkar Condition in fℛ,T Gravity

open access: yesAdvances in Astronomy, 2021
In the present work, we investigate the existence of compact star model in the background of fℛ,T gravity theory, where ℛ represents the Ricci scalar and T refers to the energy-momentum tensor trace.

Multi-Hot Compact Network Embedding [PDF]

open access: yesProceedings of the 28th ACM International Conference on Information and Knowledge Management, 2019
Network embedding, as a promising way of the network representation learning, is capable of supporting various subsequent network mining and analysis tasks, and has attracted growing research interests recently. Traditional approaches assign each node with an independent continuous vector, which will cause memory overhead for large networks.

Non-Compact Symplectic Toric Manifolds [PDF]

open access: yes, 2015
A key result in equivariant symplectic geometry is Delzant's classification of compact connected symplectic toric manifolds. The moment map induces an embedding of the quotient of the manifold by the torus action into the dual of the Lie algebra of the ...

A Lightcone Embedding of the Twin Building of a Hyperbolic Kac-Moody Group [PDF]

open access: yes, 2020
Let A be a symmetrizable hyperbolic generalized Cartan matrix with Kac-Moody algebra g = g(A) and (adjoint) Kac-Moody group G = G(A)=$\langle\exp(ad(t e_i)), \exp(ad(t f_i)) \,|\, t\in C\rangle$ where $e_i$ and $f_i$ are the simple root vectors. Let $(B^+

Quantifying soil complexity using network models of soil porous structure [PDF]

open access: yesNonlinear Processes in Geophysics, 2013
This paper describes an investigation into the properties of spatially embedded complex networks representing the porous architecture of soil systems. We suggest an approach to quantify the complexity of soil pore structure based on the node-node link ...

Weakly compact embedding of non-commutative symmetric spaces [PDF]

open access: yesE-Journal of Analysis and Applied Mathematics
In this paper, we prove that the embeddings of certain well-known symmetric spaces are weakly compact. Our main results concern noncommutative Lorentz and Marcinkiewicz spaces on finite von Neumann algebras.

Task-Optimized Word Embeddings for Text Classification Representations

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
Word embeddings have introduced a compact and efficient way of representing text for further downstream natural language processing (NLP) tasks. Most word embedding algorithms are optimized at the word level.

Reflections on Dubinskiĭ’s nonlinear compact embedding theorem [PDF]

open access: yesPublications de l'Institut Mathematique, 2012
We present an overview of a result by Yuli? Andreevich Dubinski? [Mat. Sb. 67 (109) (1965); translated in Amer. Math. Soc. Transl. (2) 67 (1968)], concerning the compact embedding of a seminormed set in Lp(0, T;A0), where A0 is a Banach space and p 2 [1,1]; we establish a variant of Dubinski??s theorem, where a seminormed nonnegative cone ...
