Deficiency Indices For Fourth-Order Matrix Differential Operators in Hilbert Spaces
We determine the deficiency indices for the 2nth-order Matrix differential operators, where $n=2$. The absolutely continuous spectrum is located and finally, the existence of a self-adjoint operator extension is proved.
