Polyakov, E. On partial recursive functions with recursive graph. (Russian) Zbl 0541.03020 Algebraic systems, Interuniv. Collect. Sci. Works, Ivanovo 1981, 174-175 (1981). [For the entire collection see Zbl 0513.00006.] Two classes of partial recursive functions are presented, each giving a trivial answer to the main question stated in a paper by V. A. Dushskij [Mat. Zametki 5, 261-267 (1969; Zbl 0184.018)].
