Strings in Nontrivial Gravitino and Ramond-ramond Backgrounds
In this paper we discuss deformations of the BRST operator of the fermionic string. These deformations preserve inlpotency of the BRST operator and correspond to turning on infinitesimal Gravitino and Ramond-Ramond spacetime fields. [email protected] One of the outstanding problems of string theory is to understand the equations of motion for the fields of the theory ( massless and...
متن کاملEvery Nontrivial Knot in S Has Nontrivial A-polynomial
We show that every nontrivial knot in the 3-sphere has a nontrivial A-polynomial. In Theorem 1 of [3], Kronheimer and Mrowka give a proof of the following remarkable theorem, thereby establishing the truth of the Property P conjecture. Theorem 0.1 (Kronheimer-Mrowka). Let K be any nontrivial knot in S and let M(r) be the manifold obtained by Dehn surgery on K with slope r with respect to the st...
متن کاملConnected Correlators in Random Geometries
We analyze correlation functions in a toy model of a random geometry interacting with matter. We show that in general the connected correlator will contain a long–range scaling part which is in some sense a remnant of the disconnected part. This result supports the previously conjectured general form of correlation functions. We discuss the interplay between matter and geometry and the role of ...
متن کاملNontrivial spontaneous synchronization.
The collective behavior of an ensemble of multimode stochastic oscillators is investigated. The oscillators are pulse coupled; they are able to emit pulses and to detect the pulses emitted by the others. As a function of the output intensity in the system they can operate in different modes having different pulsing periods. The system is designed to optimize the output intensity around a fixed ...
متن کاملCorrelators in AdS3 string theory
The computation of two and three point functions in the Coulomb gas free field approach to string theory in the SL(2,R)/U(1) black hole background is reviewed. An interesting relation arises when comparing the results obtained using two different screening operators. The formalism is then modified to study string theory propagating in AdS3 which is considered as the direct product of the SL(2)/...
