Properness without Elementaricity
We present reasons for developing a theory of forcing notions which satisfy the properness demand for countable models which are not necessarily elementary sub-models of some (H(χ),∈). This leads to forcing notions which are “reasonably” definable. We present two specific properties materializing this intuition: nep (non-elementary properness) and snep (Souslin non-elementary properness) and al...
متن کاملThe Bounded Axiom A Forcing Axiom
We introduce the Bounded Axiom A Forcing Axiom(BAAFA). It turns out that it is equiconsistent with the existence of a regular Σ2-correct cardinal and hence also equiconsistent with BPFA. Furthermore we show that, if consistent, it does not imply the Bounded Proper Forcing Axiom(BPFA).
متن کاملTHE URYSOHN AXIOM AND THE COMPLETELY HAUSDORFF AXIOM IN L-TOPOLOGICAL SPACES
In this paper, the Urysohn and completely Hausdorff axioms in general topology are generalized to L-topological spaces so as to be compatible with pointwise metrics. Some properties and characterizations are also derived
متن کاملProperness for Scaled Gauged Maps
We prove properness of moduli stacks of gauged maps satisfying a stability conditition introduced by Mundet [42] and Schmitt [48]. The proof combines a git construction of Schmitt [48], properness for twisted stable maps by Abramovich-Vistoli [1], a variation of a boundedness argument due to Ciocan-Fontanine-Kim-Maulik [13], and a removal of singularities for bundles on surfaces in Colliot-Thél...
متن کاملA-properness and Fixed Point Theorems for Dissipative Type Maps
The A-proper class arises naturally when one considers the approximation solvability of nonlinear equations, that is, obtaining solutions of infinite-dimensional problems as limits of solutions of related finite-dimensional problems. The class was first introduced by Petryshyn, who made many important contributions to the theory, see, for example, [17, 18] for a good account of this. The A-prop...
