Stability theorems for chiral bag boundary conditions
We study asymptotic expansions of the smeared L2-traces Fe−tP 2 and FPe−tP 2 , where P is an operator of Dirac type and F is an auxiliary smooth endomorphism. We impose chiral bag boundary conditions depending on an angle θ. Studying the θ-dependence of the above trace invariants, θindependent pieces are identified. The associated stability theorems allow one to show the regularity of the eta f...
متن کاملMore on Mixed Boundary Conditions and D-branes Bound States
In this article, applying different types of boundary conditions; Dirichlet, Neumann, or Mixed, on open strings we realize various new brane bound states in string theory. Calculating their interactions with other D-branes, we find their charge densities and their tension. A novel feature of (p− 2, p) brane bound state is its ”non-commutative” nature which is manifestly seen both in the open st...
متن کاملChiral Bag Boundary Conditions on the Ball
Local boundary conditions for spinor fields are expressed in terms of a 1parameter family of boundary operators, and find applications ranging from (supersymmetric) quantum cosmology to the bag model in quantum chromodynamics. The present paper proves that, for massless spinor fields on the Euclidean ball in dimensions d = 2, 4, 6, the resulting ζ(0) value is independent of such a θ parameter, ...
متن کاملHeat Kernel Coefficients for Chiral Bag Boundary Conditions
We study the asymptotic expansion of the smeared L-trace of f e 2 where P is an operator of Dirac type, f is an auxiliary smooth smearing function which is used to localize the problem, and chiral bag boundary conditions are imposed. Special case calculations, functorial methods and the theory of ζand η-invariants are used to obtain the boundary part of the heat-kernel coefficients a1 and a2.
متن کاملHorizon Branes and Chiral Strings
String Theory is known to be one possible model to unify all the known forces of the Nature by a universal concept, that of strings. All fundamental particles, including gravitons with a given energy, are supposed to be oscillating states of tensive open or closed strings. The string concept introduces some non-locality in the gravitational interactions, making the self-interacting Feynman diag...
