Annotation-free delineation of prokaryotic homology groups. [PDF]

open access: yesPLoS Computational Biology, 2022
Phylogenomic studies of prokaryotic taxa often assume conserved marker genes are homologous across their length. However, processes such as horizontal gene transfer or gene duplication and loss may disrupt this homology by recombining only parts of genes,

Homology groups in CR-warped products of complex space forms [PDF]

open access: yesHeliyon
In the present paper, by using the result of Lawson-Simons [15], we adopt a different technique to show that there are no stable integral q-currents and a non-trivial homology group in a compact oriented CR-warped product submanifold Nn in a complex ...

On the Topology of Warped Product Pointwise Semi-Slant Submanifolds with Positive Curvature

open access: yesMathematics, 2021
In this paper, we obtain some topological characterizations for the warping function of a warped product pointwise semi-slant submanifold of the form Ωn=NTl×fNϕk in a complex projective space CP2m(4).

The Homology of Warped Product Submanifolds of Spheres and Their Applications

open access: yesMathematics, 2023
The aim of the current article is to formulate sufficient conditions for the Laplacian and a gradient of the warping function of a compact warped product submanifold Σβ1+β2 in a unit sphere Sd that provides trivial homology and fundamental groups.

On the homology groups $H_k(\mathbb{C}\Omega_n)$, $k=1, ..., n$

open access: yesResearches in Mathematics, 2021
In the paper the homology groups of the $(2n+1)$-dimensional CW-complex $\mathbb{C}\Omega_n$ are investigated. The spaces $\mathbb{C}\Omega_n$ consist of complex-valued functions and generalize the widely known in the approximation theory spaces ...

The homology groups $H_{n+1} \left( \mathbb{C}\Omega_n \right)$

open access: yesResearches in Mathematics, 2022
The topic of the paper is the investigation of the homology groups of the $(2n+1)$-dimensional CW-complex $\mathbb{C}\Omega_n$. The spaces $\mathbb{C}\Omega_n$ consist of complex-valued functions and are the analogue of the spaces $\Omega_n$, widely ...

Persistent homology of groups [PDF]

open access: yesJournal of Group Theory, 2011
We introduce and investigate notions of persistent homology for p-groups and for coclass trees of p-groups. Using computer techniques we show that persistent homology provides fairly strong homological invariants for p-groups of order at most 81. The strength of these invariants, and some elementary theoretical properties, suggest that persistent ...
