چکیده
Let ϕ be a ℤ/2ℤ-spin structure on closed oriented surface Σ g of genus g≥4. We determine generating set the stabilizer in mapping class group consisting Dehn twists about an explicit collection 2g+1 curves . If g=3 then we odd ℤ/4ℤ-spin 6 curves.

Subgroups of Mapping Class Groups Generated by Three Dehn Twists
It has been shown that the mapping class group of a genus g ≥ 2 closed surface can be generated by 2g + 1 Dehn twists. Little is known, however, about the structure of those mapping class groups. This paper is an attempt to explain the structure of subgroups of the mapping class group of a closed surface of genus g ≥ 2 which are generated by three Dehn twists. 1 Background and Notation This pap...
متن کاملGenerating the Surface Mapping Class Group by Two Elements
Wajnryb proved in [W2] that the mapping class group of an orientable surface is generated by two elements. We prove that one of these generators can be taken as a Dehn twist. We also prove that the extended mapping class group is generated by two elements, again one of which is a Dehn twist.
متن کاملExotic iterated Dehn twists
Consider cotangent bundles of exotic spheres, with their canonical symplectic structure. They admit automorphisms which preserve the part at infinity of one fibre, and which are analogous to the square of a Dehn twist. Pursuing that analogy, we show that they have infinite order up to isotopy (inside the group of all automorphisms with the same behaviour).
متن کاملDehn twists on the boundary
A homeomorphism of a 3-manifold M is said to be Dehn twists on the boundary when its restriction to ∂M is isotopic to the identity on the complement of a collection of disjoint simple closed curves in ∂M . In this paper, we give various results about such collections of curves and the associated homeomorphisms. In particular, if M is compact, orientable, irreducible and ∂M is a single torus, an...
متن کاملDehn Twists and Invariant Classes
A degeneration of compact Kähler manifolds gives rise to a monodromy action on Betti moduli space H (X,G) = Hom(π1(X), G)/G over smooth fibres with a complex algebraic structure group G being either abelian or reductive. Assume that the singularities of the central fibre is of normal crossing. When G = C, the invariant cohomology classes arise from the global classes. This is no longer true in ...
