DENSITY-1-BOUNDING AND QUASIMINIMALITY IN THE GENERIC DEGREES.

We consider the question “Is every nonzero generic degree a density-1-bounding generic degree?” By previous results [8] either resolution of this question would answer an open question concerning the structure of the generic degrees: A positive result would prove that there are no minimal generic de...
