DESCRIPTION:Abstract. Adding a single Cohen real
to L provides us with a lattice of intermediate mo
dels, but if we only consider models of ZFC, these
models are all somehow very similar (except L its
elf). Without assuming the Axiom of Choice in thos
e intermediate models we have a very different pic
ture. We will discuss the construction of the Bris
tol model, which is a model between L and L[c], wh
ich does not have the form L(x) for any set x.

\n\n Adding a single Cohen real to L provides
us with a lattice of intermediate models, but if w
e only consider models of ZFC, these models are al
l somehow very similar (except L itself). Without
assuming the Axiom of Choice in those intermediate
models we have a very different picture. We will
discuss the construction of the Bristol model, whi
ch is a model between L and L[c], which does not h
ave the form L(x) for any set x.
