In this paper, we introduce the category and the homotopy category of edge-colored digraphs and construct the functorial homology theory on the foundation of the path homology theory provided by Grigoryan, Muranov, and Shing-Tung Yau. We give the con

The subject of our article is the pattern of companies’ behavior, being the result of two effects: the inertia effect (actions based on routines) and the prediction effect (actions based on expectations). The aim of the analysis was to identify and

Abstract Cryopreservation is crucial for conserving genetic diversity in endangered species including the critically endangered group of sturgeons (Acipenseridae), but it can compromise sperm quality and protein profiles. Although cryopreservation wi

Abstract Background Sturgeon species are living fossils that exhibit unique reproductive characteristics, and elucidation of the molecular processes governing the formation and quality of sturgeon eggs is crucial. However, comprehensive data on the p

We introduce the weighted path homology on the category of weigh\-ted directed hypergraphs and describe conditions of homotopy invariance of weighted path homology groups. We give several examples that explain the nontriviality of the introduced noti

We describe various path homology theories constructed for a directed hypergraph. We introduce the category of directed hypergraphs and the notion of a homotopy in this category. Also, we investigate the functoriality and the homotopy invariance of t

The Atlantic sturgeon (Acipenser oxyrinchus) faces unique conservation challenges due to its extended maturation period and irregular spawning patterns, which restrict its reproductive capacity. Therefore, in order to overcome these difficulties we h
