For a system of first-order partial differential equations in a form not investigated earlier, we consider a variant of the Goursat problem and prove the existence and uniqueness of the problem.
Keywords: system of equations with a shift of arguments of sought-for function, system of functional differential equations
Mots-clés : Goursat problem.
