Endomorphism Type of P(3m + 1,3)

Mathematics, 2023
There are six different classes of endomorphisms for a graph. The sets of these endomorphisms always form a chain under the inclusion of sets. In order to study these different endomorphisms more systematically, Böttcher and Knauer proposed the concept ...

Endomorphism Spectra of Double Fan Graphs

Mathematics, 2020
There are six different classes of endomorphisms for a graph. The sets of these endomorphisms always form a chain under the inclusion of sets. For a more systematic treatment of different endomorphisms, Böttcher and Knauer proposed the concepts of the ...

Endomorphism Spectra of Double-Edge Fan Graphs

Mathematics, 2023
There are six classes of endomorphisms for a graph. The sets of these endomorphisms form a chain under the inclusion of sets. In order to systematically study these endomorphisms, Böttcher and Knauer defined the concepts of the endomorphism spectrum and ...

Descending endomorphism graphs of groups

AKCE International Journal of Graphs and Combinatorics, 2023
We define a new type of graph of a group with reference to the descending endomorphisms of the group. A descending endomorphism of a group is an endomorphism that induces a corresponding endomorphism in every homomorphic image of the group. We define the

Quotients of Torus Endomorphisms and Lattès-Type Maps [PDF]

Arnold Mathematical Journal, 2020
AbstractWe show that if an expanding Thurston map is the quotient of a torus endomorphism, then it has a parabolic orbifold and is a Lattès-type map.

A Gelfand–Beurling Type Formula for Heights on Endomorphism Rings

Journal of Number Theory, 2000
Let \(V\) be a finite dimensional vector space over a number field \(K\). Then the spectral height \(H(T)\) of an endomorphism \(T\in\text{End}(V)\) is defined as the (suitably normalized) product of the spectral radii at all completions \(K_v\) of \(K\). It is shown that the spectral height is canonical on \(\text{End}(V)\) in the sense that we have \(

Enumerating Problems Concerning Endomorphisms of Double Vertex Wheel Graphs

Journal of Mathematics
We can define six classes of endomorphisms on a graph, and they always form a chain based on set inclusion. The concepts of endomorphism type and endomorphism spectrum were introduced by Böttcher and Knauer in 1992.
