New methods in spectral theory of -body Schrödinger operators
T. Adachi, K. Itakura, K. Ito +1
We develop a new scheme of proofs for spectral theory of the -body Schrödinger operators, reproducing and extending a series of sharp results under minimum conditions. Our main…
Stationary scattering theory on mainifolds, I
K. Ito, E. Skibsted
We study spectral theory for the Schrodinger operator on manifolds possessing an escape function. A particular class of examples are manifolds with Euclidean and/or hyperbolic ends…
Stationary scattering theory on manifolds, II
K. Ito, E. Skibsted
Based on our previous study [IS2] we develop fully the stationary scattering theory for the Schrodinger operator on a manifold possessing an escape function. A particular class of…
Further discussion of Tomboulis' approach to the confinement problem
K. R. Ito, E. Seiler
We discuss in some detail certain gaps and open problems in the recent paper by E. T. Tomboulis, which claims to give a rigorous proof of quark confinement in 4D lattice Yang-Mills…
Local exponents and infinitesimal generators of canonical transformations on Boson Fock spaces
F. Hiroshima, K. R. Ito
A one-parameter symplectic group $\{e^{t\dA}\}_{t\in\RR}$ derives proper canonical transformations on a Boson Fock space. It has been known that the unitary operator implemen…
Extended Superconformal Algebras from Classical and Quantum Hamiltonian Reduction
K. Ito, J. O. Madsen, J. L. Petersen
We consider the extended superconformal algebras of the Knizhnik-Bershadsky type with -algebra like composite operators occurring in the commutation relations, but with generato…
