Full Reflection at a Measurable Cardinal
A stationary subset S of a regular uncountable cardinal re ects fully at regular cardinals if for every stationary set T of higher order consisting of regular cardinals there exists an 2 T such that S \ is a stationary subset of . Full Re ection states that every stationary set re ects fully at regular cardinals. We will prove that under a slightly weaker assumption than having Mitchell order +...
متن کاملThe first measurable cardinal can be the first uncountable regular cardinal at any successor height
We use techniques due to Moti Gitik to construct models in which for an arbitrary ordinal ρ, אρ+1 is both the least measurable and least regular uncountable cardinal.
متن کاملWalleye and Northern Pike
Introductions of nonnative walleye (Stizostedion vitreum) and northern pike (Esox lucius) have created popular recreational fisheries in many Northwestern waters. Rising demand for expanded angling opportunities for these species, especially walleye, has been met with growing concern about longterm risks associated with the introduction of a top predator. Proposed introductions are often contro...
متن کاملLaschamp Excursion at Mono Lake?
The Laschamp Geomagnetic Excursion (ca. 41 ka) and a related increase of cosmogenic nuclides provides a global tie point among sedimentary and ice core records. In the Wilson Creek Formation, Mono Lake, California, the Laschamp Excursion has not been recognized although the so-called Mono Lake excursion was found in the section with an estimated age of about 28 14C ka. However, our reevaluation...
متن کاملWeak reflection at the successor of a singular cardinal
The notion of stationary reflection is one of the most important notions of combinatorial set theory. We investigate weak reflection, which is, as its name suggests, a weak version of stationary reflection. Our main result is that modulo a large cardinal assumption close to 2hugeness, there can be a regular cardinal κ such that the first cardinal
