Special complex manifolds [PDF]

Journal of Geometry and Physics, 1999
We introduce the notion of a special complex manifold: a complex manifold (M,J) with a flat torsionfree connection \nabla such that (\nabla J) is symmetric.

Comparison of manifold learning algorithms for identifying geochemical anomalies associated with copper mineralization [PDF]

Scientific Reports
The Baiyin district, situated within the northern Qilian orogenic belt, hosts the largest concentration of copper mineral resources in Gansu Province, Northwestern China. Geochemical anomaly patterns are crucial indicators for mineral exploration in this

On transversely holomorphic foliations with homogeneous transverse structure

Pracì Mìžnarodnogo Geometričnogo Centru, 2023
In this paper we study transversely holomorphic foliations of complex codimension one with a transversely homogeneous complex transverse structure. We prove that the only cases are the transversely additive, affine and projective cases. We shall focus on

On Almost Norden Statistical Manifolds

Entropy, 2022
We consider a statistical connection ∇ on an almost complex manifold with (pseudo-) Riemannian metric, in particular the Norden metric. We investigate almost Norden (statistical) manifolds under the condition that the almost complex structure J is ...

MANIFOLD MATCHING COMPLEXES

Mathematika, 2020
43 pages, 32 figures Version 2 added a reference. Version 2 extends the theorems by weakening the hypotheses from combinatorial to homology manifolds, but shows the manifolds that occur are all ...

Submanifolds of Almost-Complex Metallic Manifolds

Mathematics, 2023
Our paper aims to study the geometry of submanifolds of an almost-complex metallic manifold. We give an example of this type of manifold, and reveal the fundamental properties of structure induced on submanifolds.

Effects of embedded distance measurements interacting with modeling approaches on empirical dynamical model predictions

Ecological Indicators, 2023
Empirical Dynamic Modeling (EDM) has been a powerful tool for complex ecosystem prediction by providing an equation-free modelling framework. Theoretically, it allows future ecosystem behavior to be predicted by connecting current state to the similar ...

Manifold Background-Aware Correlation Filter Target Tracking [PDF]

Jisuanji kexue yu tansuo, 2023
In order to solve the problem that target is easy to lose in complex scenes such as similar background, occlusion, fast motion and motion blur, a new manifold background-aware correlation filter tracking algorithm is proposed.

Locally Conformally Flat Doubly Twisted Product Complex Finsler Manifolds

Journal of Mathematics, 2022
Let M1×λ1,λ2M2,F be a doubly twisted product manifold of two strongly pseudoconvex complex Finsler manifolds M1,F1 and M2,F2. In this study, we give a characterization of locally conformally flat doubly twisted product complex Finsler manifold.
