Add to ORKGIn this paper, we discuss the deficiency index problem for the product differential operators which are generated by a general ordinary quasi-differential expressions , , … , each of order with complex coefficients in the direct sum ⨁ ୀ ൫ ൯ of spaces of functions defined on each of the separate intervals in the cases of regular and singular end-points. The domains of these operators are described in terms of boundary conditions featuring -solutions of the differential equations. These results extend those of formally symmetric expression studied in [1, 2], [8 -11] an
