    Algebraic Geometry Realization of Quantum Hall Soliton

    Full text link
    Using Iqbal-Netzike-Vafa dictionary giving the correspondence between the H2_{2} homology of del Pezzo surfaces and p-branes, we develop a new way to approach system of brane bounds in M-theory on S1\mathbb{S}^{1}. We first review the structure of ten dimensional quantum Hall soliton (QHS) from the view of M-theory on S1\mathbb{S}^{1}. Then, we show how the D0 dissolution in D2-brane is realized in M-theory language and derive the p-brane constraint eqs used to define appropriately QHS. Finally, we build an algebraic geometry realization of the QHS in type IIA superstring and show how to get its type IIB dual. Others aspects are also discussed. Keywords: Branes Physics, Algebraic Geometry, Homology of Curves in Del Pezzo surfaces, Quantum Hall Solitons.Comment: 19 pages, 12 figure

    Classification of N=2 supersymmetric CFT_{4}s: Indefinite Series

    Full text link
    Using geometric engineering method of 4D N=2\mathcal{N}=2 quiver gauge theories and results on the classification of Kac-Moody (KM) algebras, we show on explicit examples that there exist three sectors of N=2\mathcal{N}=2 infrared CFT4_{4}s. Since the geometric engineering of these CFT4_{4}s involve type II strings on K3 fibered CY3 singularities, we conjecture the existence of three kinds of singular complex surfaces containing, in addition to the two standard classes, a third indefinite set. To illustrate this hypothesis, we give explicit examples of K3 surfaces with H34_{3}^{4} and E10_{10} hyperbolic singularities. We also derive a hierarchy of indefinite complex algebraic geometries based on affine ArA_{r} and T%_{(p,q,r)} algebras going beyond the hyperbolic subset. Such hierarchical surfaces have a remarkable signature that is manifested by the presence of poles.Comment: 12 pages, 2 figure

    Geometric Engineering of N=2 CFT_{4}s based on Indefinite Singularities: Hyperbolic Case

    Full text link
    Using Katz, Klemm and Vafa geometric engineering method of N=2\mathcal{N}=2 supersymmetric QFT4_{4}s and results on the classification of generalized Cartan matrices of Kac-Moody (KM) algebras, we study the un-explored class of N=2\mathcal{N}=2 CFT4_{4}s based on \textit{indefinite} singularities. We show that the vanishing condition for the general expression of holomorphic beta function of N=2\mathcal{N}=2 quiver gauge QFT4_{4}s coincides exactly with the fundamental classification theorem of KM algebras. Explicit solutions are derived for mirror geometries of CY threefolds with \textit{% hyperbolic} singularities.Comment: 23 pages, 4 figures, minor change

    On F-theory Quiver Models and Kac-Moody Algebras

    Full text link
    We discuss quiver gauge models with bi-fundamental and fundamental matter obtained from F-theory compactified on ALE spaces over a four dimensional base space. We focus on the base geometry which consists of intersecting F0=CP1xCP1 Hirzebruch complex surfaces arranged as Dynkin graphs classified by three kinds of Kac-Moody (KM) algebras: ordinary, i.e finite dimensional, affine and indefinite, in particular hyperbolic. We interpret the equations defining these three classes of generalized Lie algebras as the anomaly cancelation condition of the corresponding N =1 F-theory quivers in four dimensions. We analyze in some detail hyperbolic geometries obtained from the affine A base geometry by adding a node, and we find that it can be used to incorporate fundamental fields to a product of SU-type gauge groups and fields.Comment: 13 pages; new equations added in section 3, one reference added and typos correcte

    On ADE Quiver Models and F-Theory Compactification

    Full text link
    Based on mirror symmetry, we discuss geometric engineering of N=1 ADE quiver models from F-theory compactifications on elliptic K3 surfaces fibered over certain four-dimensional base spaces. The latter are constructed as intersecting 4-cycles according to ADE Dynkin diagrams, thereby mimicking the construction of Calabi-Yau threefolds used in geometric engineering in type II superstring theory. Matter is incorporated by considering D7-branes wrapping these 4-cycles. Using a geometric procedure referred to as folding, we discuss how the corresponding physics can be converted into a scenario with D5-branes wrapping 2-cycles of ALE spaces.Comment: 21 pages, Latex, minor change

    On Local Calabi-Yau Supermanifolds and Their Mirrors

    Full text link
    We use local mirror symmetry to study a class of local Calabi-Yau super-manifolds with bosonic sub-variety V_b having a vanishing first Chern class. Solving the usual super- CY condition, requiring the equality of the total U(1) gauge charges of bosons \Phi_{b} and the ghost like fields \Psi_{f} one \sum_{b}q_{b}=\sum_{f}Q_{f}, as \sum_{b}q_{b}=0 and \sum_{f}Q_{f}=0, several examples are studied and explicit results are given for local A_{r} super-geometries. A comment on purely fermionic super-CY manifolds corresponding to the special case where q_{b}=0, \forall b and \sum_{f}Q_{f}=0 is also made.\bigskipComment: 17 page
