It studies sets which possess relatively simple definitions (in contradistinction to the ideas of arbitrary sets and various higher power-sets, which the semi-intuitionists rejected as meaningless) called projective or analytic sets. It is common to count it, in the literature on the foundations of mathematics, the name notwithstanding, as "ordinary mathematics", in contradistinction to set theory. | |
