   …construct a non-linearizable action of the symmetric group $S_3$, the smallest nonabelian group, on $M$ by automorphisms. We also construct a non-linearizable action of $S_3$ on free metabelian associative algebras…

   …of order $v$, denoted by $\operatorname{SQS}(v)$, is called cyclic if it admits $\mathbb Z_v$ as a group of automorphisms acting regularly on its point set. A cyclic system is called symmetric cyclic, or S-cyclic, if…

3. On the group of automorphisms of the escaping sets of H\'{e}non maps math.CV · 19 Oct · 3 hits

   In this article, we provide an explicit description of $\operatorname{Aut}_1(I_H^+)$, the group of automorphisms of the escaping set $I_H^+$ of a H\'enon map that induce the identity on its fundamental group.…

   …of dimension two and higher. As usual, the classification is reduced to the description of the orbits of the automorphism group of the algebra on the subspaces of its second cohomology space with trivial coefficients.…

   …minimal immersions of this type for Hurwitz surfaces and other families of %Riemann surfaces with large automorphism group. Finally, we explicitly construct a conformal minimal equivariant immersion of the Klein…

   …by declaring that their relations are precisely the two-tensors vanishing on the graph of a translation automorphism on a quartic complex elliptic curve and the vertex pairs where the vertices are the singular…

   …degree $m-2$, although every holomorphic map to a projective space is constant. We compute their connected automorphism groups and show that they admit no maximal torus action. They are Hopf-surface bundles over…
