Hamiltonian quantum chromodynamics has been formulated on a discrete lattice, in an attempt to calculate the hadronspectrum using strong coupling expansions. Previous attempts have involved including an irrelevant four-fermion interaction term in the Hamiltonian. As well as making the quark content of the zeroth order states the same as that of the simple additive quark model, this term splits the infinite zeroth order degeneracies of the original Hamiltonian. In this paper we calculate the masses of low lying states in the absence of such a term, using an effective Hamiltonian method to solve the degeneracy problem. We discuss the problems of continuing our series to the continuum limit in the presence of level repulsion. 相似文献

On the state stability of a system of integro-differential equations of nonstationary aeroelasticity
We consider a process of nonstationary aeroelasticity, which is described by a system of integro-dijferential equations that cannot be solved for the derivative. We formulate necessary and sufficient conditions, in terms of Lyapunov functionals, for the exponential stability of such a system with respect to the metric of an infinite Hilbert space. A formula is given for the total derivative of a Lyapunov functional via the initial equations of motion.Translated from Vychislitel'naya i Prikladnaya Matematika, No. 70, pp. 112–121, 1990. 相似文献

The asymptotic behavior of state-constrained semilinear optimal control problems for distributed-parameter systems with variable
compact control zones is investigated. We derive conditions under which the limiting problems can be made explicit.
