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 کاملUrban Wildlife: Can We Live with Them?
A survey of Extension Wildlife Specialists in the U.S. provided a basis for estimating the magnitude of urban wildlife damage and control in this country. Response to the 9-question mail questionnaire was good (76 percent) following the single mailing to all Extension Wildlife Specialists or people in similar positions listed in the national directory.

The continuing rapid age shift in recent years from predominately a younger to an older population in America and many other countries is a problem of great concern.

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...
