Twodimensional density matrix and its equations. Scalar and fermionic fields
Abstract
Twodimensional density matrix is introduced which (its Wigner transform) satisfies the system of equations: one is the Neumann equation and the other is the new equation. These equations allow one to formulate quantum field theory in the phase space and may serve as input equations of the relativistic quantum statistical mechanics.
