Abstract: We consider the Mellin–Barnes integral that corresponds to a monomial function of a solution to a system of $n$ algebraic equations in $n$ variables. For $n=3$ we prove that a known necessary condition for convergence for the Mellin–Barnes integral is also sufficient.
Keywords: algebraic equations, Mellin–Barnes integral, convergence.
