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 کاملA general framework for geometric dualities for varieties of algebras
We set up a framework that subsumes many important dualities in mathematics (Birkhoff, Stone, Priestly, Baker-Beynon, etc.) as well as the classical correspondence between polynomial ideals and affine varieties in algebraic geometry. Our main theorems provide a generalisation of Hilbert’s Nullstellensatz to any (possibly infinitary) variety of algebras. The common core of the above dualities be...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Geometric Unification of Evolutionary Algorithms
Evolutionary algorithms are only superficially different and can be unified within an axiomatic geometric framework by abstraction of the solution representation. This framework describes the evolutionary search in a representation-independent way, purely in geometric terms, paving the road to a general theory of evolutionary algorithms. It also leads to a principled design methodology for the ...
