Unification of String Dualities
We argue that all conjectured dualities involving various string, Mand F theory compactifications can be ‘derived’ from the conjectured duality between type I and SO(32) heterotic string theory, T-dualities, and the definition of Mand F theories. (Based on a talk given at the conference on ‘Advanced Quantum Field Theory’, Le Londe-les-Maures, France, Aug.31-Sept.5, 1996, in memory of Claude Itz...
متن کاملSymmetrically reduced Galileon equations and solutions
The maximally complicated arbitrary-dimensional “maximal” Galileon field equations simplify dramatically for symmetric configurations. Thus, spherical symmetry reduces the equations from the D− to the two-dimensional Monge-Ampere equation, axial symmetry to its cubic extension etc. We can then obtain explicit solutions, such as spherical or axial waves, and relate them to the (known) general, b...
متن کاملScaling Dualities
In this paper rst we prove four fundamental theorems of the alternative, called scaling dualities, characterizing exact and approximate solvability of four signi cant conic problems in nite dimensional spaces, de ned as: homogeneous programming (HP), scaling problem (SP), homogeneous scaling problem (HSP), and algebraic scaling problem (ASP). Let be a homogeneous function of degree p > 0, K a p...
متن کاملUnity of Superstring Dualities
The effective action for type II string theory compactified on a six torus is N = 8 supergravity, which is known to have an E 7 duality symmetry. We show that this is broken by quantum effects to a discrete subgroup, E 7 (Z), which contains both the T-duality group O(6, 6; Z) and the S-duality group SL(2; Z). We present evidence for the conjecture that E 7 (Z) is an exact 'U-duality' symmetry o...
متن کاملMany Facets of Dualities
In this paper we survey results related to homomorphism dualities for graphs, and more generally, for finite structures. This is related to some of the classical combinatorial problems, such as colorings of graphs and hypergraphs, and also to recently intensively studied Constraint Satisfaction Problems. On the other side dualities are related to the descriptive complexity and First Order defin...
