Spin(8, ℂ)-Higgs bundles fixed points through spectral data
Open MathematicsLet XX be a compact Riemann surface of genus g≥2g\ge 2. The geometry of the moduli space ℳ(Spin(8,C)){\mathcal{ {\mathcal M} }}\left({\rm{Spin}}\left(8,{\mathbb{C}})) of Spin(8,C){\rm{Spin}}\left(8,{\mathbb{C}})-Higgs bundles over XX is of great interest

Extensions of Steiner Triple Systems
Journal of Combinatorial Designs, Volume 33, Issue 3, Page 94-108, March 2025.ABSTRACT In this article, we study extensions of Steiner triple systems by means of the associated Steiner loops. We recognize that the set of Veblen points of a Steiner triple system corresponds to the center of the Steiner loop. We investigate extensions of Steiner loops, focusing in particular on the case of Schreier extensions, which provide a ...

Outer automorphisms of locally finite p-groups
Journal of Algebra, 2003 Let \(G\) be any group. Recall that the set \(\text{Inn}(G)\) of all inner automorphisms of \(G\) is a normal subgroup of \(\Aut(G)\). The quotient group \(\Aut(G)/\text{Inn}(G)\) is called the group of all outer automorphisms of \(G\) and is denoted by \(\text{Out}(G)\). Several authors have studied outer automorphism groups in the literature.

A Kazhdan group with an infinite outer automorphism group
Surveys in Mathematics and its Applications, 2011 D. Kazhdan has introduced in 1967 the Property (T) for local compact groups. In this article we prove that for $n\geq 3$ and $m \in \mathbb{N}$ the group $SL_n(\textbf{K})\ltimes \mathcal{M}_{n,m}(\textbf{K})$ is a Kazhdan group having the outer automorphism group infinite.

End invariants of the group of outer automorphisms of a free group
Topology, 1995 It is known that every finitely generated group has 0, 1, 2 or infinitely many ends. If the group is finitely presented, then the number of ends is equal to the number of ends of any simply connected complex on which the group acts freely with finite quotient.
