ON A BOUNDARY-VALUE PROBLEM WITH DATA ON NONCHARACTERISTIC INTERSECTING LINES FOR SYSTEMS OF HYPERBOLIC EQUATIONS WITH MIXED DERIVATIVE

摘要

We consider a boundary-value problem with data located on noncharacteristic intersecting lines for systems of hyperbolic equations with mixed second-order derivative. Using the method of additional parameters, we establish the existence of a unique classical solution of this problem and develop a procedure for finding this solution.
