Iterated extended ultrapowers and supercompactness without choice

AbstractWorking in ZF + DC with no additional use of the axiom of choice, we show how to iterate the extended ultrapower construction of Spector (1988, 1991). This generalizes the technique of iterated ultrapowers to choiceless set theory. As an application, we prove the following theorem: Assume V = LU[Pκ(λ)] + “κ is λ-supercompact with normal ultrafilter U” + DC. Then for every sufficiently large regular cardinal ρ, there exists a set-generic extension V[G] of the universe in which there exists for some σ a set S ⊆ Pρ(σ) for which one can define an elementary embedding j mapping V to LD[S], where D is the filter in V[G] generated by the closed unbounded filter (according to V) on Pρ(σ). Moreover, we have j(κ) = ρ, j(λ) = σ, j(Pκ(λ)) = S (which is Pρ(σ) according to LD[S]), and j(itU) = D ∩ LD[S] i s a normal ultrafilter in LD[S] on Pρ(σ)

Visual binding of luminance, motion and disparity edges

AbstractVisual binding of edge segments embedded in noise and created by luminance, motion and disparity contrasts were studied in three experiments. The results showed that path formation was limited by the same rules across all attributes tested. The first experiment showed that binding could be accomplished with either attribute used in isolation. The second experiment showed that closed paths were easier to detect than open paths irrespectively of the attributes used to create the path elements. No additive effects were found in either Experiment 1 or 2 when the path elements were created with several attributes superimposed on the same positions, compared to when only one attribute was used along the path. In Experiment 3 it was found that when another attribute was added between the positions of the first attribute along the path, so that two attributes alternated along the path, the performance of path detection was better than expected by probability summation estimated from the single attribute conditions. These results provide evidence for attribute-invariant Gestalt laws and provide clues about the underlying neural mechanisms
