Flow Equations for N Point Functions and Bound States
We discuss the exact renormalization group or flow equation for the effective action and its decomposition into one particle irreducible N point functions. With the help of a truncated flow equation for the four point function we study the bound state problem for scalar fields. A combination of analytic and numerical methods is proposed, which is applied to the Wick-Cutkosky model and a QCD-mot...
متن کاملRenormalization flow of bound states
A renormalization group flow equation with a scale-dependent transformation of field variables gives a unified description of fundamental and composite degrees of freedom. In the context of the effective average action, we study the renormalization flow of scalar bound states which are formed out of fundamental fermions. We use the gauged Nambu–Jona-Lasinio model at weak gauge coupling as an ex...
متن کاملAskey-wilson Type Functions, with Bound States
The two linearly independent solutions of the three-term recurrence relation of the associated Askey-Wilson polynomials, found by Ismail and Rahman in [19], are slightly modified so as to make it transparent that these functions satisfy a beautiful symmetry property. It essentially means that the geometric and the spectral parameters are interchangeable in these functions. We call the resulting...

China Full list of author information is available at the end of the article Abstract In this paper, proving the pullback asymptotic compactness of processes by the aid of a contractive function in space X0, we prove the existence of a pullback attractor for N-dimensional non...
متن کاملAsymptotic Dynamics of Nonlinear Schrödinger Equations with Many Bound States
We consider a nonlinear Schrödinger equation with a bounded local potential in R3. The linear Hamiltonian is assumed to have three or more bound states with the eigenvalues satisfying some resonance conditions. Suppose that the initial data is localized and small of order n in H1, and that its ground state component is larger than n3−ǫ with ǫ > 0 small. We prove that the solution will converge ...
