Towards The Moduli Space of Extended Partial Isometries
نویسندگان
چکیده
Abstract Partial Isometries are important constructs that help give nontrivial solutions once a simple solution is known. We generalize this notion to Extended Partial Isometries and include operators which have right inverses but no left inverses (or vice versa). We find a large class of such operators and show the moduli space to contain the Hilbert Scheme of Points. Further, we apply this technique to find instanton solutions of a noncommutative N = 1 supersymmetric gauge theory in six dimensions and show that this construction yields nontrivial solutions for other noncommutative gauge theories. The analysis is done in one complex dimension and the generalization of the result to higher dimensions is shown.

Partial Spontaneous Breaking of Global Supersymmetry ∗ †
During the last two years, vast progress has been made in our understanding of the nonperturbative dynamics of supersymmetric quantum field theory and string theory. N = 2 supersymmetric theories present a manifold of vacua (so called moduli space) corresponding to the arbitrary values of scalar fields in the flat directions of the potential; while the physics is determined at a given point on ...
متن کاملGlobalization of the partial isometries of metric spaces and local approximation of the group of isometries of Urysohn space
We prove the equivalence of the two important facts about finite metric spaces and universal Urysohn metric spaces U, namely theorem A and theorem B below: Theorem A (Approximation): The group of isometry ISO(U) contains everywhere dense locally finite subgroup; Theorem G(Globalization): For each finite metric space F there exists another finite metric space F̄ and isometric imbedding j of F to ...
متن کاملRigidity of quasi-isometries for symmetric spaces and Euclidean buildings
for all x ∈ X . Quasi-isometries occur naturally in the study of the geometry of discrete groups since the length spaces on which a given finitely generated group acts cocompactly and properly discontinuously by isometries are quasi-isometric to one another [Gro]. Quasi-isometries also play a crucial role in Mostow’s proof of his rigidity theorem: the theorem is proved by showing that equivaria...
متن کاملAlgebraic realizations of cyclic isometries of the rational K3 lattice
We prove: For all n and all n-cylic isometriesφ : ΛQ → ΛQ of the rational K3 lattice there exists an algebraic realization of φ, i.e. marked algebraic K3 surfaces (S,ηS) and (M,ηM), whereM is a moduli space of sheaves on S, and a Hodge isometry ψ : H2(S,Q)→ H2(M,Q) such that φ = ηM ◦ψ ◦ η−1 S . 1 Facts about cyclic isometries We need the existence of a triple ((S,ηS), (M,ηM),ψ) to have a point ...
