Some Functional Solutions of the Yang-Baxter Equation
D. Ts. Stoyanov
A general functional definition of the infinite dimensional quantum R-matrix satisfying the Yang-Baxter equation is given. A procedure for extracting a finite dimensional R-matrix…
On the Bound States in a Non-linear Quantum Field Theory of a Spinor Field with Higher Derivatives
A. D. Mitov, M. N. Stoilov, D. Ts. Stoyanov
We consider a model of quantum field theory with higher derivatives for a spinor field with quartic selfinteraction. With the help of the Bethe-Salpeter equation we study the probl…
A Model of Quantum Electrodynamics with Higher Derivatives
D. Ts. Stoyanov
A new version of application Pauli-Villars regularized Green functions in the quantum field theory using higher derivatives is proposed. In this version the regularizing mass i…
