Non-Isomorphic Cayley Graphs of Metacyclic Groups of Order 8p with the Same Spectrum
MathematicsThe spectrum of a graph Γ, denoted by Spec(Γ), is the multiset of eigenvalues of its adjacency matrix. A Cayley graph Cay(G,S) of a finite group G is called Cay-DS (Cayley graph determined by its spectrum) if, for any other Cayley graph Cay(G,T), Spec ...

Decompositions of nearly complete digraphs into t isomorphic parts
Discussiones Mathematicae Graph Theory, 2009 An arc decomposition of the complete digraph Kₙ into t isomorphic subdigraphs is generalized to the case where the numerical divisibility condition is not satisfied. Two sets of nearly tth parts are constructively proved to be nonempty.

Bio-Inspired Tendon-Driven Finger Design With Isomorphic Ligamentous Joint
IEEE Access, 2020 This paper suggests a novel type of bio-inspired finger design in that the joints that compose the finger mimic the features of human finger joints. They have isomorphic structures but different movements, further, there is no friction between bones in ...

Infants help a non-human agent. [PDF]
PLoS ONE, 2013 Young children can be motivated to help adults by sympathetic concern based upon empathy, but the underlying mechanisms are unknown. One account of empathy-based sympathetic helping in adults states that it arises due to direct-matching mirror-system ...

Isomorphic bisections of cubic graphs [PDF]
, 2021 Graph partitioning, or the dividing of a graph into two or more parts based on certain conditions, arises naturally throughout discrete mathematics, and problems of this kind have been studied extensively. In the 1990s, Ando conjectured that the vertices

Геодинамика и тектонофизика, 2021 In the South Urals, we have identified and investigated two platinum-bearing formations – ophiolite chromitebearing complexes, and the Khudolaz differentiated mafic-ultramafic complex with sulfide Cu-Ni mineralization.

IEEE Access, 2020 Although some algebraic theories such as partial order set, lattice and their properties on fuzzy set had been studied, these algebraic theories on fuzzy automata (FA) have not been discussed at present. For saving the energy of the battery so as to make

On the solution of the Graph Isomorphism Problem Part 1
CoRR, 2010 The presented material is devoted to the equivalent conversion from the vertex graphs to the edge graphs. We suggest that the proved theorems solve the problem of the isomorphism of graphs, the problem of the graph's enumeration with the help of the effective algorithms without their preliminary plotting, etc. The examining of the transformation of the

Turán and Ramsey problems for alternating multilinear maps
Discrete Analysis, 2023 Turán and Ramsey problems for alternating multilinear maps, Discrete Analysis 2023:12, 22 pp. Ramsey's theorem (in its finite version) states that for every positive integer $k$ there exists a positive integer $n$ such that every graph with $n$ vertices

Classifying unavoidable Tverberg partitions
Journal of Computational Geometry, 2017 Let $T(d,r) = (r-1)(d+1)+1$ be the parameter in Tverberg's theorem, and call a partition $\mathcal I$ of $\{1,2,\ldots,T(d,r)\}$ into $r$ parts a Tverberg type.
