Comparison and Oscillation Theorems for singular Ultrahyperbolic Equations
In this study, comparison and oscillation theorems are given for a class of singular ultra- hyperbolic partial differential equations in a domain HxG Em +n , where H is the domain bounded by two concentric m-spheres having centers at £ in Em and G is a bounded regular do main in Ea . By using a suitable coordinate transformation the considered equation reduces to a singular hyperbolic equation.
