Was Sierpinski Right? III: Can Continuum-cc. Times c.c.c. be Continuum-c.c.?

چکیده
We prove the consistency of: if B1, B2 are Boolean algebras satisfying the c.c.c. and the 20 -c.c. respectively then B1 × B2 satisfies the 20 -c.c. We start with a universe with a Ramsey cardinal (less suffice).

Dominating Analytic Families
Let A be an analytic family of sequences of sets of integers. We show that either A is dominated or it contains a continuum of almost disjoint sequences. From this we obtain a theorem by Shelah that a Suslin c.c.c. forcing adds a Cohen real if it adds an unbounded real.
متن کاملLarge Continuum, Oracles Sh895
Our main theorem is about iterated forcing for making the continuum larger than ℵ 2. We present a generalization of [Sh:669] which dealt with oracles for random, (also for other cases and generalities), by replacing ℵ 1 , ℵ 2 by λ, λ + (starting with λ = λ <λ > ℵ 1). Well, we demand absolute c.c.c. So we get, e.g. the continuum is λ + but we can get cov(meagre) = λ and we give some applications...
متن کاملA Continuum Model For Stone-wales Defected Carbon Nanotubes
In this paper, a continuum model is proposed so that a Stone-Wales (SW) defected carbon nanotube (CNT) is replaced by an initial circumferential crack in a continuum cylindrical shell. For this purpose, the critical energy release rate and then the fracture toughness of a defected CNT are calculated using the results of an existing atomistic-based continuum finite element simulation. Finally, t...
متن کاملInelastic Continuum Modeling of Carbon Nanotube,s Behavior Using Finite Element Method
This paper describes a continuum model for analyzing the inelastic behavior of a single walled carbon nanotube (SWCNT) in different loading conditions. Because of limitations in using molecular dynamics (and other atomic methods) to model the failure load of the SWCNT, continuum mechanics methods are considered in this paper. Based on some experimental and theoretical results, an elasto-plastic...
متن کاملWhy Y-c.c
We outline a portfolio of novel iterable properties of c.c.c. and proper forcing notions and study its most important instantiations, Y-c.c. and Y-properness. These properties have interesting consequences for partitiontype forcings and anticliques in open graphs. Using Neeman’s side condition method it is possible to obtain PFA variations and prove consistency results
