Abstract: In this note, we describe first the structure of minimal non-Iwasawa finite groups. Then we determine the minimal non-Iwasawa finite groups which are modular. Also, we find connections between minimal non-Iwasawa finite groups and the… read more here.

DOI: 10.1007/s10884-020-09877-w

Abstract: In this article we show that R.H. Bing’s pseudo-circle admits a minimal non-invertible map. This resolves a conjecture raised by Bruin, Kolyada and Snoha in the negative. The main tool is a variant of the… read more here.

Abstract: A finite group G is said to be a minimal non-????n group if G itself is not a group of nilpotency class ≤ n and all of whose proper subgroups are of nilpotency class ≤… read more here.

DOI: 10.3390/sym15051114

Abstract: In this research paper, we study 3-uniform hypergraphs H=(X,E) with circular symmetry. Two parameters are considered: the largest size α(H) of a set S⊂X not containing any edge E∈E, and the maximum number χ¯(H) of… read more here.
