Abstract
The existence of an infinite graph which is not isomorphic to a proper minor of itself was proved by Oporowski. In the present note, it is shown that an analogous result holds when immersions are considered instead of minors. The question whether or not the same is true for weak immersions remains open.

## Abstract We show that, for __r__ββ₯β2 and __k__ββ₯β3, there exists a positive constant __c__ such that for large enough __n__ there are 2 nonβisomorphic graphs on at most __n__ vertices that are __r__βramseyβminimal for the odd cycle __C__~2__k__+1~.

A graph is said to be one-regular if its automorphism group acts regularly on the set of its arcs. A construction of an infinite family of infinite one-regular graphs of valency 4 is given. These graphs are Cayley graphs of almost abelian groups and hence of polynomial growth.
We present a construction of two infinite graphs \(G_{1}, G_{2}\) and of an infinite set of graphs such that \(\mathscr{F}\) is an antichain with respect to the minor relation and, for every graph \(G\) in \(\mathscr{F}\), both \(G_{1}\) and \(G_{2}\) are subgraphs of \(G\) but no graph obtained fro
## Abstract For a graph __A__ and a positive integer __n__, let __nA__ denote the union of __n__ disjoint copies of __A__; similarly, the union of β΅~0~ disjoint copies of __A__ is referred to as β΅~0~__A__. It is shown that there exist (connected) graphs __A__ and __G__ such that __nA__ is a minor o
## Abstract Based on the terms βendβ and βcofinal spanning subtreeβ a general notion of Hamiltonicity of infinite graphs is developed. It is shown that the cube of every connected locally finite graph is Hamiltonian in this generalized sense.
