Constructing many atomic models in א 1 John Baldwin

As has been known since at least [?] and is carefully spelled out in Chapter 6 of [?], for every complete sentence ψ of Lω1,ω (in a countable vocabulary τ ) there is a complete, first order theory T (in a countable vocabulary extending τ ) such that the models of ψ are exactly the τ -reducts of the atomic models of T . This paper is written entirely in terms of the class AtT of atomic models of...

D ec 1 99 8 Evolutionary Baldwin Effect in AGN

Assuming Active Galactic Nuclei are powered by accretion onto a massive black hole we suggest that the growth of the central black hole mass due to the matter accreted over the AGN lifetime causes evolution of the luminosity and spectrum. We show that the effective temperature of the UV continuum spectrum is likely to be anti-correlated with the black hole mass and with the luminosity. We estim...
