Addendum: Π-principal hereditary orders (Nagoya Math. J. 32 (1968), 41–65)

Orders of Π-bases

We extend the scope of B. Shapirovskii’s results [6] on the order of π-bases in compact spaces and answer some questions of V. Tkachuk in [7].

Final State Interaction Effects in B+→J/ψ π+ Decay

In this research the exclusive decay of                         is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the  decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...

Does J / ψ → π + π − fix the Electromagnetic Form Factor

Hiroshima Math. J. 35 (2005), 205–249

We study reaction-di¤usion systems of propagator-controller type in the one-dimensional unit interval. When propagator di¤uses slowly, we establish the existence of transition layer equilibria by using singular perturbation expansions and a Lyapunov-Schmidt reduction method. Our approach to the existence also enables us to simultaneously obtain a stability criterion for the layer equilibria.

Doc. Math. J. Dmv 1 Quantum Computing

The Church-Turing thesis says that a digital computer is a universal computational device; that is, it is able to simulate any physically realizable computational device. It has generally been believed that this simulation can be made eecient so that it entails at most a polynomial increase in computation time. This may not be true if quantum mechanics is taken into consideration. A quantum com...
