The Flabby Class Group of a Finite Cyclic Group
This is an expository paper on work of Endo and Miyata which leads to a computation of the flabby class group of a finite cyclic group.
متن کاملFuzzy subgroups of the direct product of a generalized quaternion group and a cyclic group of any odd order
Bentea and Tu{a}rnu{a}uceanu~(An. c{S}tiinc{t}. Univ. Al. I.Cuza Iac{s}, Ser. Nouv{a}, Mat., {bf 54(1)} (2008), 209-220)proposed the following problem: Find an explicit formula for thenumber of fuzzy subgroups of a finite hamiltonian group of type$Q_8times mathbb{Z}_n$ where $Q_8$ is the quaternion group oforder $8$ and $n$ is an arbitrary odd integer. In this paper weconsider more general grou...
متن کاملOn the nilpotency class of the automorphism group of some finite p-groups
Let $G$ be a $p$-group of order $p^n$ and $Phi$=$Phi(G)$ be the Frattini subgroup of $G$. It is shown that the nilpotency class of $Autf(G)$, the group of all automorphisms of $G$ centralizing $G/ Fr(G)$, takes the maximum value $n-2$ if and only if $G$ is of maximal class. We also determine the nilpotency class of $Autf(G)$ when $G$ is a finite abelian $p$-group.
متن کاملCoinvariants and the regular representation of a cyclic P-group
We consider an indecomposable representation of a cyclic p-group Z pr over a field of characteristic p. We show that the top degree of the corresponding ring of coinvariants is less than (r 2+3r)pr 2 . This bound also applies to the degrees of the generators for the invariant ring of the regular representation.
متن کاملTHE FULL AUTOMORPHISM GROUP OF A CYCLIC p-GONAL SURFACE
If p is prime, a compact Riemann surface X of genus g ≥ 2 is called cyclic p-gonal if it admits a cyclic group of automorphisms Cp of order p such that the quotient space X/Cp has genus 0. If in addition Cp is not normal in the full automorphism A, then we call X a non-normal p-gonal surface. In the following we classify all non-normal p-gonal surfaces. A.
