Vector‐Based and Machine Learning Approaches for Pore Network Parameters Analysis
Geophysical Prospecting, Volume 74, Issue 1, January 2026.ABSTRACT Accurate characterization of pore structures in carbonate rocks is critical for evaluating fluid flow and storage capacity in subsurface reservoirs, a key concern in geophysical exploration and reservoir engineering. This study proposes a hybrid digital rock physics workflow that integrates deep learning–based segmentation, vectorial geometric

Riemannian Maps To Almost Hermitian Manifolds
, 2017 In this chapter, we study Riemannian maps from Riemannian manifolds to almost Hermitian manifolds. In section 1, we study invariant Riemannian maps, that is, the image of derivative map is invariant under the almost complex structure of the base manifold.

Siegel–Veech constants for cyclic covers of generic translation surfaces
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract We compute the asymptotic number of cylinders, weighted by their area to any nonnegative power, on any cyclic branched cover of any generic translation surface in any stratum. Our formulae depend only on topological invariants of the cover and number‐theoretic properties of the degree: in particular, the ratio of the related Siegel–Veech ...

On Canonical-Type Connections on Almost Contact Complex Riemannian Manifolds
, 2015 We consider a pair of smooth manifolds, which are the counterparts in the even-dimensional and odd-dimensional cases. They are separately an almost complex manifold with Norden metric and an almost contact manifolds with B-metric, respectively.

Riemannian Maps From Almost Hermitian Manifolds
, 2017 In this chapter, we study Riemannian maps from almost Hermitian manifolds to Riemannian manifolds. In section 1, we study holomorphic Riemannian maps as a generalization of holomorphic submersions and obtain a characterization of such maps. In section 2,

Riemannian Curvature of a Sliced Contact Metric Manifold [PDF]
, 2018 Contact geometry become a more important issue in the mathematical world with the workswhich had done in the 19th century. Many mathematicians have made studies on contactmanifolds, almost contact manifolds, almost contact metric manifolds and contact ...

Unsupervised shape clustering using diffusion map [PDF]
, 2008 The quotient space of all smooth and connected curves represented by a fixed number of boundary points is a finite-dimensional Riemannian manifold, also known as a shape manifold.

Riemannian submersions From Almost Hermitian Manifolds
, 2017 In this chapter, we introduce various new Riemannian submersions from almost Hermitian manifolds on to Riemannian manifolds. In section 1, we first review almost Hermitian manifolds and their submanifolds, and give brief information about holomorphic ...
