New reals: Can live with them, can live without them
Judah and Shelah [3] proved that countable support iterations of proper forcings preserve the ω-bounding property (see 2.2 here). In his book Proper and Improper Forcing [8, XVIII §3] Shelah gave several cases of general preservation theorems for proper countable support iterations (the proofs tend to be hard to digest, though). In this paper we deal with “Case A”. A simplified version of this ...
متن کاملNew Reals: Can Live with Them, Can Live without Them (draft)
A simplified version of this case appeared in Section 5 of Goldstern’s Tools for your forcing constructions [2]. This version uses the additional requirement that every forcing of the iteration adds a new real. Note that this requirement is met in most applications, but the case of forcings not adding reals has important applications as well (and not adding reals is generaly not preserved under...

The authors analyzed data from all antidepressant studies submitted to the Food and Drug Administration for registration (including failed studies w...
متن کاملCan’t live with them, can’t live without them? Balancing mating and competition in two-sex populations
Two-sex populations are usually studied through frequency-dependent models that describe how sex ratio affects mating, recruitment and population growth. However, in two-sex populations, mating and recruitment should also be affected by density and by its interactions with the sex ratio. Density may have positive effects on mating (Allee effects) but negative effects on other demographic proces...
