Simplex polynomial in complex networks and its applications to compute the Euler characteristic

Frontiers in Computational Neuroscience
In algebraic topology, a k-dimensional simplex is defined as a convex polytope consisting of k + 1 vertices. If spatial dimensionality is not considered, it corresponds to the complete graph with k + 1 vertices in graph theory. The alternating sum of the

Invariant structural learning: concept formation as hypergraph attractor dynamics

Сучасний стан наукових досліджень та технологій в промисловості
Subject of study. The subject of study is the formation of object-class concepts in machine-learning systems as a process of structural and parametric reduction of hypergraph representations, rather than as the optimization of a loss function. Objective.

Monochromatic triangles in three-coloured graphs [PDF]

, 2013
In 1959, Goodman [9] determined the minimum number of monochromatic triangles in a complete graph whose edge set is 2-coloured. Goodman (1985) [10] also raised the question of proving analogous results for complete graphs whose edge sets are coloured ...

Decompose complete tripartite graph into asteroidal graph

, 2010
碩士在本篇論文中，我們主要是探討一個完全三分圖Kp,q,r是否能分割成三角星狀圖(簡稱星狀圖)。 我們先獲得Kp,q,r可以分割成星狀圖的必要條件，同時利用拉丁方陣進而得到若Kp,q,r可以分割成星狀圖，則Knp,nq,nr亦可以分割成星狀圖，對於一些特殊型態的p、q、r，我們獲得Kp,q,r的星狀圖分割，同時我們將所有q為6的倍數且q>=r>=q/2、5q/2>=p>=q的Kq,q,r與Kp,q,q分割成星狀圖，最後我們給予K2n,2n,2n分割成循環星狀圖的建構法。In this thesis,
