In this paper we classify the non-symplectic automorphisms of prime order p 3 acting on IHS K3[2]. As an application of our results, we construct the rst known examples of non-natural non-symplectic automorphisms of order 3 on IHS K3[2]. This comes from the study of non-symplectic automorphisms of order 3 on a special.

    RIGIDITY OF COMMUTATIVE NON-HYPERBOLIC ACTIONS BY TORAL AUTOMORPHISMS ZHIREN WANG Abstract. Berend gives necessary and sufficient conditions on a Zr-action α on a torus Td by toral automorphisms in order for every orbit be either finite or dense. One of these conditions is that on every common eigendirection of the Zr-action there is an. groups of orbit spaces of finite group actions which we prove in §1. We then prove our main theorem for surfaces in §2 and for graphs in §3. 1 The homology of quotient spaces If G is a group and M is a G-representation over a field F (that is, an F-vector space on which G acts linearly; this is the same as a F[G]-module), then the.

    In general, an Automorphism is a symmetry preserving bijective function (permutation) from a Mathematical entity to itself. Here is an explanation using Group Theory: In the context of Group Theory, an Automorphism is an Isomorphism from a Group. Abstract: Let $\C$ be a sequence of multisets of subspaces of a vector space $\F_q^k$. We describe a practical algorithm which computes a canonical form and the stabilizer of $\C$ under the group action of the general semilinear by:

Consider a group G acting on a set orbit of an element x in X is the set of elements in X to which x can be moved by the elements of orbit of x is denoted by G⋅x: ⋅ = {⋅ ∣ ∈}.

The defining properties of a group guarantee that the set of orbits of (points x in) X under the action of G form a partition of associated equivalence relation is defined by saying x ∼ y if. Kondracki and J.

In mathematics, an automorphism is an isomorphism from a mathematical object to itself. It is, in some sense, a symmetry of the object, and a way of mapping the object to itself while preserving all of its structure. The set of all automorphisms of an object forms a group, called the automorphism is, loosely speaking, the symmetry group of the object.

It is easy to check that this action is well-defined. Clearly there is only one orbit and the stabiliser of the trivial left coset H is H itself. Lemma Let G be a group acting transitively on a set S and let H be the stabiliser of a point s ∈ S. Let L be the set of left cosets of H in Size: KB.

The equivalence classes of this action are called orbits. The action is said to be transitive if there is only one orbit (neces-sarily the whole of S). Proof. Given s2Snote that es= s, so that s˘sand ˘is re exive. If sand t2Sand s˘tthen we may nd g2Gsuch that t= gs.

Outer space with the action of Out(F n) can be thought of as analogous to a homogeneous space with the action of an arithmetic group, or to the Teichm˜uller space of a surface with the action of the mapping class group of the Size: KB.

Automorphism, in mathematics, a correspondence that associates to every element in a set a unique element of the set (perhaps itself) and for which there is a companion correspondence, known as its inverse, such that one followed by the other produces the identity correspondence (i); i.e., the.

The automorphisms of C n are given by σ l: C n → C n,g 7→gl for 1 ≤ l ≤ n − 1, gcd(l,n) = 1. The set of orbits on C n under the action of Aut(C n) is in natural bijection with the set of divisors of n: for every divisor t of n the set of elements of order t forms an orbit under the.

We show that the orbit type stratification is, in general, not locally finite by giving an example of an action of a compact group on an infinite-dimensional vector space with infinitely many orbit types, see Example Finally, we introduce the notion of smooth regularity of a Cited by: 2.

In this situation each element of kforms an orbit, so we study only the orbits of Aut(K=k) on K k. Our Con-jecture asserts that if Aut(K=k) acts on K kwith nitely many orbits, then kand K are either both nite or both algebraically closed. This conjecture contains Theorem as.

Abstract. a) In the seventies, several papers of A.M. Vershik, I.M. Gelfand and M.I. Graev ([19], [20], [21]) initiated the research of non located continuous irreducible unitary representations of current groups of the type C k (M, G) where M is a smooth Riemannian manifold, and G a finite dimensional Lie group.

We present a new construction of tubular neighborhoods in (possibly infinite dimensional) Riemannian manifolds M, which allows us to show that if G is an arbitrary group acting isometrically on M, then every G-invariant submanifold with locally trivial normal bundle has a G-invariant total tubular neighborhood.
