Descent Relations in Type 0A/0B
نویسنده
چکیده
The type 0 theories have twice as many stable D-branes as the type II theories. In light of this added complication, we find the descent relations for D-branes in the type 0A and 0B theories. In addition, we work out how the two types of D-branes differ in their couplings to NS-NS fields. E-mail: [email protected]

A non-technical overview on gravity in two dimensions is provided. Applications discussed in this work comprise 2D type 0A/0B string theory, Black Hole evaporation/thermodynamics, toy models for quantum gravity, for numerical General Relativity in the context of critical collapse and for solid state analogues of Black Holes. Mathematical relations to integrable models, non-linear gauge theories...
متن کاملEvaluation of pronuclear morphology as the only selection criterion for further embryo culture and transfer: results of a prospective multicentre study M.Montag1 and H.van der Ven on behalf of the German Pronuclear Morphology Study
BACKGROUND: The aim was to study zygote evaluation based on pronuclear morphology under the German embryo protection law, according to which only a maximum of three zygotes are allowed to be cultured for embryo transfer. METHODS: In this prospective multicentre study, a total of 512 treatment cycles was performed at 10 centres, between November 1999 and October 2000. Zygotes were classified int...
متن کاملNS Fivebranes in Type 0 String Theory ∗
The massless degrees of freedom of type 0 NS5-branes are derived. A non-chiral, purely bosonic spectrum is found in both type 0A and 0B. This non-chirality is confirmed by a one-loop computation in the bulk. An interpretation of the spectra in terms of “type 0 little strings” is proposed. The type 0B NS5-brane is conjectured to be dual to a bound state of certain D5-branes, which is argued to h...
متن کاملFlux-vacua in Two Dimensional String Theory
We analyze the two dimensional type 0 theory with background RR-fluxes. Both the 0A and the 0B theory have two distinct fluxes q and q̃. We study these two theories at finite temperature (compactified on a Euclidean circle of radius R) as a function of the fluxes, the tachyon condensate μ and the radius R. Surprisingly, the dependence on q, q̃ and μ is rather simple. The partition function is the...
