Title: o-minimal expansions of ordered fields, convex valuations,
and (trans)series<br>
<br>
Abstract<br>
<br>
The first half of the talk will be a gentle introduction to
o-minimality, presenting some history, motivation, examples, and
covering some basic fundamental results (cell-decomposition,
Miller's growth dichotomy). A brief interlude on the theory of
(T-)convex valuations on o-minimal expansions of fields will follow.
The last part will be dedicated to discuss some connections with
fields formal generalized series and transseries, and on how these
can be used to explicitly construct and describe models of a given
complete o-minimal theory expanding the theory of real closed field.<br>
