> *"Imaginaries in fields with additional structure"*
>>
>> An imaginary in a first order structure M is a finite tuple modulo a
>> definable equivalence relation. In some cases (e.g. real closed or
>> algebraically closed fields), every imaginary is interdefinable with a
>> tuple from the structure, and M is said to eliminate imaginaries. In
>> general, one aims to classify imaginaries up to interdefinability.
>>
>>

>  In this talk, I will give an overview on what is known about
>> imaginaries in fields with extra structure (valuation, derivation,
>> automorphism etc.) Using the classification of imaginaries in algebraically
>> closed valued fields (Haskell-Hrushovski-Macpherson) together with results
>> on higher amalgamation in valued fields of residue characteristic 0, I will
>> indicate how imaginaries of "finite rank" may be classified in valued
>> fields with automorphism.
