  TOPIC: Categoricity and unidimensionality
A countable first-order theory is said to be uncountably categorical if it
has a unique model(up to isomorphism)in every uncountable cardinality.
The class of unidimensional theories is a natural extension of the class of
uncountably categorical theories. Geometric model theory has developed from
categoricity theory: characterizations of categorical theories and some
classifications of their pregeometries(matroids). The analysis of
unidimensional theories has led to the development of new machinary in 
geometric model theory as well.
