SUMMARY:Tutte Colloquium - László Végh
CLASS:PUBLIC
DESCRIPTION:TITLE: On complete classes of valuated matroids\n\nSpeaker:\n 
 László Végh\n\nAffiliation:\n London School of Economics\n\nZoom:\n Ple
 ase email Emma Watson\n\nABSTRACT:\n\nValuated matroids were introduced b
 y Dress and Wenzel in 1992. They\nare a central object in discrete convex 
 analysis\, and play important\nroles in other areas such as mathematical e
 conomics and tropical\ngeometry. Finding a constructive characterization\,
  i.e.\, showing that\nall valuated matroids can be derived from a simple c
 lass by some basic\noperations has been a natural question proposed in var
 ious contexts.
