Sei \(\Gamma_a\) die Klasse der endlichen zusammenhängenden Graphen vom Minimalgrad mindestens \(a\), und sei \(\Gamma_{a,k}\) die Klasse der \(G \in \Gamma_a\) mit der Taillenweite mindestens \(k\). Satz 1: Für \(q \geq q_n\) ist jedes \(G \in \Gamma_{3,q}\) auf \(K_n\) kontrahierbar. Der Verf. führt den Begriff \(k\)-zyklisch-eckenzusammenhängend ein.

High-Girth matrices and polarization [PDF]
The girth of a matrix is the least number of linearly dependent columns, in contrast to the rank which is the largest number of linearly independent columns. This paper considers the construction of {\it high-girth} matrices, whose probabilistic girth is close to its rank.

The 4-girth-thickness of the complete multipartite graph
The $g$-girth-thickness $\theta(g,G)$ of a graph $G$ is the smallest number of planar subgraphs of girth at least $g$ whose union is $G$. In this paper, we calculate the $4$-girth-thickness $\theta(4,G)$ of the complete $m$-partite graph $G$ when each ...

Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Let \(G\) denote a strongly-connected digraph with \(n\) nodes, girth \(g\), and diameter \(D\). The author shows that if \(G\) has \(t\) nodes of out-degree one, then \(D\leq n-g+ t\). He also shows that if \(r\) denotes the minimum out-degree of \(G\), then \(g\leq \max\{\lceil n/r\rceil, 2r- 2\}\). This last result implies that when \(n\geq 2r^2- 3r+

Tanner
Girth plays an important role in the design of low-density parity-check (LDPC) codes. Motivated by the works on the girth of some classes of Tanner quasi-cyclic (QC) LDPC codes, e.g., Tanner (3, 5), (3, 7), (3, 11), and (5, 7) codes, we, in this paper ...

Purpose To evaluate the biomechanical performance of the sewing machine‐like suture (SMS) technique against three established techniques (two cinch‐loop (TCL), modified Mason‐Allen (MMA), and double Mason‐Allen (DMA)) for transtibial pull‐out repair of posterior medial meniscal root tear (PMMRT) in a porcine model.
