Boundaries in Field Theory  

In General > s.a. hamiltonian dynamics; symplectic structures.
* Issues: Choice of boundary terms in the action, or other functionals such as conserved quantities, and boundary conditions for (bulk) field theories, taking into account possible corner terms where the boundary is not smooth and/or possible null portions of the boundary.
@ Boundary dynamics: Bordag et al PRD(02)ht/01 [Robin boundary conditions].
@ Fields propagating across junctions: Fomin & Shtanov CQG(02)ht/00; > s.a. actions for general relativity, metric matching conditions.
@ Related topics: Kheyfets & Wheeler IJTP(86) [boundary of a boundary principle]; Galvan qp/98 [measure on boundary conditions]; Zuber ht/00-ln [rational conformal field theory].

Bulk and Boundary Relationship > s.a. AdS-cft [and Maldacena conjecture]; holography; topology.
@ Specific spacetimes: Keski-Vakkuri PRD(99)ht/98 [BTZ black holes].

Field Theories on Manifolds with Boundary
> Examples: see actions for general relativity; BF theories; branes; canonical general relativity; dilaton; electromagnetism and in curved spacetime; gauge theories; gravitational energy; hamiltonian systems; quasilocal general relativity; supersymmetric field theories; topological field theories.

Boundaries in Quantum Field Theory > s.a. klein-gordon; QED; types of yang-mills gauge theories.
