ABSTRACT In this note, we discuss the definition of the S1-convexity Phenomenon. We first make use of some
results we have attained for in the past, such as those contained in, to refine the
definition of the phenomenon. We then observe that easy counter-examples to the
claim extends K0 are found. Finally, we make use of one theorem from and a new theorem
that appears to be a supplement to that one to infer that does not properly extend K0 in both its original and its
