✦ Synopsis

AN EXTENSION OF THE HYPERPROJECTIVE HIERARCHY by ELIOT D. FELDNAN in College Park, Maryland (U.S.A.)I) l) This paper is part of the author's Ph. D. dissertation written at Stevens Institute of Technology under the gracious direction of Professor STEPHEN L. BLOOM to whom the author wishes to express his deepest appreciation. J. W. ADDISON in "Some consequences of axiom of constructibifity", Fund. Math. 46 (1959), proves on pages 340-341 that the axiom of constructibility implies the existence of a projective (indeed d:) well-ordering of all of NN.
