A model decomposition method for the real-time non-line-of-sight imaging
iScienceSummary: Real-time non-line-of-sight (NLOS) imaging faces a fundamental trade-off between acquisition efficiency and reconstruction quality. Although transient methods achieve high visual fidelity, they depend on extensive data collection. Regularization-

Vector fields on nonorientable surfaces
International Journal of Mathematics and Mathematical Sciences, 2003 A one-to-one correspondence is established between the germs of functions and tangent vectors on a NOS X and the bi-germs of functions, respectively, elementary fields of tangent vectors (EFTV) on the orientable double cover of X.

Fixed Points of Local Actions of Lie Groups on Real and Complex 2-Manifolds
Axioms, 2015 I discuss old and new results on fixed points of local actions by Lie groups G on real and complex 2-manifolds, and zero sets of Lie algebras of vector fields. Results of E. Lima, J. Plante and C. Bonatti are reviewed.

On the partial parallelizable manifolds and associated invariants
Annals of the West University of Timisoara: Mathematics and Computer ScienceOur idea is to use the global diffeomorphism group G (M) to study certain properties of differentiable manifolds endowed with global vector fields. We define a partial parallelizable manifold (p.p.m.) as a couple (M, ρp), where ρp is a global partial ...

Small data solutions of the Vlasov-Poisson system and the vector field method
, 2015 The aim of this article is to demonstrate how the vector field method of Klainerman can be adapted to the study of transport equations. After an illustration of the method for the free transport operator, we apply the vector field method to the Vlasov ...

Gauge Theories in Noncommutative Homogeneous K\"ahler Manifolds
, 2014 We construct a gauge theory on a noncommutative homogeneous K\"ahler manifold, where we employ the deformation quantization with separation of variables for K\"ahler manifolds formulated by Karabegov.

On related vector fields of capillary surfaces
International Journal of Mathematics and Mathematical Sciences, 1981 In this paper, some necessary and sufficient conditions are given for the related vector fields of capillary surfaces to be Killing, conformal Killing, and homothetic conformal Killing vectors in the n-dimensional domain Ω, and a construction of ...

A Note on Geodesic Vector Fields
Mathematics, 2020 The concircularity property of vector fields implies the geodesicity property, while the converse of this statement is not true. The main objective of this note is to find conditions under which the concircularity and geodesicity properties of vector ...

Alignment of vector fields on manifolds via contraction mappings
Учёные записки Казанского университета: Серия Физико-математические науки, 2018 According to the manifold hypothesis, high-dimensional data can be viewed and meaningfully represented as a lower-dimensional manifold embedded in a higher dimensional feature space. Manifold learning is a part of machine learning where an intrinsic data

Concurrent Vector Fields on Lightlike Hypersurfaces
Mathematics, 2020 Concurrent vector fields lying on lightlike hypersurfaces of a Lorentzian manifold are investigated. Obtained results dealing with concurrent vector fields are discussed for totally umbilical lightlike hypersurfaces and totally geodesic lightlike ...
