文摘

Some sufficient conditions and some sufficient and necessary conditions are established for the oscillation of a class of odd-order delay parabolic differential equations of the form Formula Not Shown where N is an odd integer, Formula Not Shown is a bounded domain in Formula Not Shown with a smooth boundary Formula Not Shown, and Formula Not Shown is the Laplacian operation with three different boundary conditions. To some extent, our results extended and improved the oscillatory results of some references. Meanwhile, we corrected some mistakes in a main conclusion of reference (J. Comput. Appl. Math. 147 (2002) 263).
