The derivation algebra and automorphism group of the electrical Lie algebra of type D5
上海师范大学学报. 自然科学版In this paper, we mainly investigate the derivation algebra and automorphism group of type D5 electrical Lie algebra. We prove that the outer derivations are four-dimensional, and the automorphism group Aut $\mathcal{L} \cong \mathbb{C}^* \ltimes\left ...

𝜔! can be a nontrivial automorphism group
, 1991 Under the axiom "there are ω 1 {\omega _1} cofinal Cohen reals," the symmetric group on ω \omega is the nontrivial automorphism group of a thin-tall superatomic Boolean algebra ...

On the automorphism group of a tree
Journal of Combinatorial Theory, Series B, 1977 AbstractIt is shown that H = Γ(T)v is normal in G = Γ(Tv) for any tree T and any vertex v, if and only if, for all vertices u in the neighborhood N of v, the set of images of u under G is either contained in N or has precisely the vertex u in common with N and every vertex in the set of images is fixed by H.

On central endomorphisms of a group [PDF]
International Journal of Group Theory, 2015 Let Γ be a normal subgroup of the full automorphism group Aut(G) of a group G , and assume that Inn(G)≤Γ . An endomorphism σ of G is said to be {\it Γ -central} if σ induces the the identity on the factor group G/C G (Γ) .

Ree groups as automorphism groups of block designs
Examples and CounterexamplesA recent classification of flag-transitive 2-designs with parameters (v,k,λ) whose replication number r is coprime to λ gives rise to eight possible infinite families of 2-designs, some of which are with new parameters.

Alternating groups as automorphism groups of Riemann surfaces
, 2006 In this work we give pairs of generators (x, y) for the alternating groups An, 5 ≤ n ≤ 19, such that they determine the minimal genus of a Riemann surface on which An acts as the automorphism group.

ON AUTOMORPHISM GROUPS OF MATRICES
Prikladnaya diskretnaya matematika, 2010 Summary: In this paper we consider the groups of the left (right) automorphisms of matrices and their automorphism groups. Without loss of generality one can take square matrices over the ring of integers. For such a matrix, we suggest the notion of a quasiautomorphism and the correspondent notion of its quasiautomorphism group.

The Automorphism Group of Finite Godel Algebras
, 2010 We investigate the automorphism group of finite Gödel algebras, the algebraic counterpart of Gödel infinite-valued propositional logic with a finite number of variables.

Flux Landscape with enhanced symmetry not on SL(2, ℤ) elliptic points
Journal of High Energy PhysicsWe study structures of solutions for SUSY Minkowski F-term equations on two toroidal orientifolds with h 2,1 = 1. Following our previous study [1], with fixed upper bounds of a flux D3-brane charge N flux, we obtain a whole Landscape and a distribution ...
