    Abstract
  • To study a class of boundary value problems of parabolic differential equations with deviating arguments, averaging technique, Green's formula and symbol function sign(·) are used. The multi dimensional problem was reduced to a one dimensional oscillation problem for ordinary differential equations or inequalities. Two oscillatory criteria of solutions for systems of parabolic differential equations with deviating arguments are obtained.
