Recent Applications of Totally Proper Forcing

چکیده
A totally proper poset is a partially ordered set which is proper and has the property that forcing with it does not add reals This announcement has to do with various uses of these kinds of posets either by themselves or in combination with other kinds of proper posets to construct models of set the ory in which various strong topological statements hold Some of these statements have not been known to be consistent be fore at all while the consistency of others was heretofore only known in models of MA CH whereas all the models we describe here satisfy and most of them satisfy CH as well

Totally Proper Forcing and the Moore-mrówka Problem
In this paper we describe a totally proper notion of forcing that can be used to shoot uncountable free sequences through certain countably compact non-compact spaces. This is almost (but not quite!) enough to produce a model of ZFC+CH in which countably tight compact spaces are sequential — we still do not know if the notion of forcing described in the paper can be iterated without adding reals.
متن کاملFirst Countable Continua and Proper Forcing
Assuming the Continuum Hypothesis, there is a compact first countable connected space of weight א1 with no totally disconnected perfect subsets. Each such space, however, may be destroyed by some proper forcing order which does not add reals.
متن کاملNon existence of totally contact umbilical slant lightlike submanifolds of indefinite Sasakian manifolds
We prove that there do not exist totally contact umbilical proper slant lightlike submanifolds of indefinite Sasakian manifolds other than totally contact geodesic proper slant lightlike submanifolds. We also prove that there do not exist totally contact umbilical proper slant lightlike submanifolds of indefinite Sasakian space forms.
متن کامل2 00 5 Inverse Limits and Function Algebras ∗ Joan
Assuming Jensen’s principle ♦, there is a compact Hausdorff space X which is hereditarily Lindelöf, hereditarily separable, and connected, such that no closed subspace of X is both perfect and totally disconnected. The Proper Forcing Axiom implies that there is no such space. The ♦ example also fails to satisfy the CSWP (the complex version of the Stone-Weierstrass Theorem). This space cannot c...
متن کاملOn the zero forcing number of some Cayley graphs
Let Γa be a graph whose each vertex is colored either white or black. If u is a black vertex of Γ such that exactly one neighbor v of u is white, then u changes the color of v to black. A zero forcing set for a Γ graph is a subset of vertices Zsubseteq V(Γ) such that if initially the vertices in Z are colored black and the remaining vertices are colored white, then Z changes the col...
