Lovely pairs of models
We introduce the notion of a lovely pair of models of a simple theory T , generalizing Poizat’s “belles paires” of models of a stable theory and the third author’s “generic pairs” of models of an SU -rank 1 theory. We characterise when a saturated model of the theory TP of lovely pairs is a lovely pair (that is when the notion of a lovely pair is “axiomatizable”), finding an analogue of the non...
متن کاملCosmic Strings: Lovely Objects!
Cosmis strings are the most promising among the cosmological defects. They also constitute earliest possible observable strings, therefore prove vital for string theorists. Here I review different kinds of cosmological defects, then focus on the cosmic strings. I give a short theoretical derivation first and then discuss experimental efforts to detect them.
متن کاملRequiem for my lovely.
Thirty-five years ago, B.F. Skinner (1976) lamented a decreasing trend in the prevalence of cumulative records in the Journal of the Experimental Analysis of Behavior ( JEAB). The editorial began with the two memorable lines, ‘‘Evidently we have not long to wait for an issue of JEAB without a single cumulative record! I shall not miss the records so much as the kinds of experiments that could s...
متن کاملOn lovely pairs of geometric structures
We study the theory of lovely pairs of geometric structures, in particular o-minimal structures. We characterize linear" theories in terms of properties of the corresponding theory of the lovely pair. For o-minimal theories, we use Peterzil-Starchenko's trichotomy theorem to characterize for su ciently general points, the local geometry around it in terms of the thorn U rank of its type.
متن کاملLovely Pairs for Independence Relations
In the literature there are two different notions of lovely pairs of a theory T, according to whether T is simple or geometric. We introduce a notion of lovely pairs for an independence relation, which generalizes both the simple and the geometric case, and show how the main theorems for those two cases extend to our general notion.
