Spinor-spinor quasipotential in quantum electrodynamics
Theoretical and Mathematical Physics, 1987For two interacting spinor fields with equal masses and the use of relativistically invariant gauges of Lorentz type, a quasipotential is constructed in accordance with the first variant of the Logunov-Tavkhelidze potential approach. The diagrams of second order are taken into account, and the quasipotential is found in the four-component Dirac form ...

Let E be an oriented real vector bundle equipped with a metric \(\beta\) of signature (p,q). Two results are proved. A regular full isotrope of (E,\(\beta)\) induces a \(Spin^ c\) structure for (E,\(\beta)\). A Spin structure for (E,\(\beta)\) induces a Spin structure for \((D^{\perp}/D,\beta_ D)\); likewise for \(Spin^ c\) structures. Here D is a real
