On the problem of cyclization of “Little Tragedies” by A. S. Pushkin [PDF]
The article proposes a new version of the cycle-forming organization of “Little Tragedies” by A. S. Pushkin, after a brief excursion through the already existing cycle-forming concepts of a group of scenes and plays united in Russian culture under the ...

Long cycles, heavy cycles and cycle decompositions in digraphs [PDF]
Hajós conjectured in 1968 that every Eulerian \(n\)-vertex graph can be decomposed into at most $\lfloor (n-1)/2\rfloor$ edge-disjoint cycles. This has been confirmed for some special graph classes, but the general case remains open. In a sequence of papers by Bienia and Meyniel (1986), Dean (1986), and Bollobás and Scott (1996) it was analogously ...

On The Investigating Cycle Properties In The Galilean Plane G^2
The introduction of the Galilean plane within the affine plane parallels the familiar concepts of the Euclidean plane, extending the realm of geometric exploration.

THE STUDY OF ECCENTRICITY SPECTRUM AND ENERGY IN PATH AND CYCLE GRAPHS
The eccentricity matrix is one of matrices to represent graphs. The eccentricity matrix is used as a basis for calculating the eccentricity spectrum and energy. This article aims to study the concepts of eccentricity spectrum and energy in simple graphs.

Cycles intersecting edge-cuts of prescribed sizes [PDF]
We prove that every cubic bridgeless graph $G$ contains a $2$-factor which intersects all (minimal) edge-cuts of size $3$ or $4$. This generalizes an earlier result of the authors, namely that such a $2$-factor exists provided that $G$ is planar.

LIFE CYCLE OF PRODUCTS AND CYCLES [PDF]
The aim of this paper is to examine whether the development of waste recycling activities can be a source of economic fluctuations. We assume that the recycling sector has four fundamental characteristics. (i) The production factors are restricted by the production of the last period.

Several zones in southwestern Morocco were surveyed following a recent exceptional invasion of a species of cicada in May 2021, which caused significant damage, particularly in young almond plantations. The objective is to identify the cicada causing the

Monetary Cycles, Financial Cycles and the Business Cycle [PDF]
One of the most robust stylized facts in macroeconomics is the forecasting power of the term spread for future real activity. The economic rationale for this forecasting power usually appeals to expectations of future interest rates, which affect the slope of the term structure.

Clustering Cycles into Cycles of Clusters [PDF]
Summary: We study simple families of clustered graphs that are highly unconnected. We start by studying 3-cluster cycles, which are clustered graphs such that the underlying graph is a simple cycle and there are three clusters all at the same level. We show that in this case, testing the c-planarity can be done efficiently and give an efficient drawing

The Modular Irregularity Strength of C_n⊙mK_1
Let G(V, E) be a graph with order n with no component of order 2. An edge k-labeling α: E(G) →{1,2,…,k} is called a modular irregular k-labeling of graph G if the corresponding modular weight function wt_ α:V(G) → Z_n defined by wt_ α(x) =Ʃ_(xyϵE(G)) α ...
