Thermal Partition Functions for S-branes
We calculate the thermal partition functions of open strings on the S-brane backgrounds (the bouncing or rolling tachyon backgrounds) both in the bosonic and superstring cases. According to [9], we consider the discretized temperatures compatible with the pure imaginary periodicity of tachyon profiles. The “effective Hagedorn divergence” is shown to appear no matter how low temperature is chose...
متن کاملNew integral inequalities for $s$-preinvex functions
In this note, we give some estimate of the generalized quadrature formula of Gauss-Jacobi$$underset{a}{overset{a+eta left( b,aright) }{int }}left( x-aright)^{p}left( a+eta left( b,aright) -xright) ^{q}fleft( xright) dx$$in the cases where $f$ and $left| fright| ^{lambda }$ for $lambda >1$, are $s$-preinvex functions in the second sense.
متن کاملZeta Function Expression of Spin Partition Functions on Thermal AdS3
We find a Selberg zeta function expression of certain one-loop spin partition functions on three-dimensional thermal anti-de Sitter space. Of particular interest is the partition function of higher spin fermionic particles. We also set up, in the presence of spin, a Patterson-type formula involving the logarithmic derivative of zeta.
متن کاملIntersection Rules for S-Branes
We give a model-independent derivation of general intersecting rules for spacelike branes (S-branes) in arbitrary dimensions d. This is achieved by directly solving bosonic field equations for supergravity coupled to a dilaton and antisymmetric tensor fields with minimal ansätze. We compare the results with those in eleven-dimensional supergravity and other solutions. ∗e-mail address: ohta@phys...
متن کاملS-branes, Negative Tension Branes, and Cosmology
A general class of solutions of string background equations is studied and its physical interpretations are presented. These solutions correspond to generalizations of the standard black p-brane solutions to surfaces with curvature k = −1, 0. The relation with the recently introduced S-branes is provided. The mass, charge, entropy and Hawking temperature are computed, illustrating the interpret...
