Hermitian symplectic geometry and the factorisation of the scattering matrix on graphs
M. Harmer
Hermitian symplectic spaces provide a natural framework for the extension theory of symmetric operators. Here we show that hermitian symplectic spaces may also be used to describe…
Hermitian symplectic geometry and extension theory
M. Harmer
Here we give brief account of hermitian symplectic spaces, showing that they are intimately connected to symmetric as well as self-adjoint extensions of a symmetric operator. Furth…
Manipulating the electron current through a splitting
M. Harmer, A. Mikhailova, B. S. Pavlov
The description of electron current through a splitting is a mathematical problem of electron transport in quantum networks. For quantum networks constructed on the interface of na…
Inverse Scattering on Matrices with Boundary Conditions
M. Harmer
We describe inverse scattering for the matrix Schroedinger operator with general selfadjoint boundary conditions at the origin using the Marchenko equation. Our approach allows the…
The spectra of the spherical and euclidean triangle groups
M. Harmer
We derive the spectrum of the Laplace-Beltrami operator on the quotient orbifold of the non hyperbolic triangle groups.
Note on the Schwarz Triangle functions
M. Harmer
We shown the rationality of the Taylor coefficients of the inverse of the Schwarz triangle functions for a triangle group about any vertex of the fundamental domain.
