boundary 
The main idea for our approach relies on a study of the boundary theory we established for the general CAT(1) spaces.


LetD be a Hermitian symmetric space of tube type,S its Shilov boundary andG the neutral component of the group of biholomorphic diffeomorphisms ofD.


Taking a specific determination of its argument and studying its limit when approaching the Shilov boundary, we are able to define a ?valued,Ginvariant kernel for triples of mutually transversal points inS.


For every orbitGυ which is not polynomially convex we construct an analytic annulus or strip inG?υ with the boundary inGυ.


Such properties are expressed using the Furstenberg boundary of the associated symmetric space ? × ?.


Orbits of triples in the Shilov boundary of a bounded symmetric domain


A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one.


We show that D is uniquely determined from boundary measurements corresponding two appropriately chosen Neumann datas.


The sampling theorem is a Kramertype sampling theorem, but unlike Kramer's theorem the sampling points are not necessarily eigenvalues of some boundary value problems.


We study boundary value problems for the timeharmonic form of the Maxwell equations, as well as for other related systems of equations, on arbitrary Lipschitz domains in the threedimensional Euclidean space.

By producing a L2 convergent Neumann series, we prove the invertibility of the elastostatics and hydrostatics boundary layer potentials on arbitrary Lipschitz domains with small Lipschitz character and 3D polyhedra with large dihedral angles.
