Classifications of Cohen-Macaulay modules - The base ring associated to   a transversal polymatroid
  In this thesis, we focus on the study of the base rings associated to some transversal polymatroids. A transversal polymatroid is a special kind of discrete polymatroid. Discrete polymatroids were introduced by Herzog and Hibi \cite{HH} in 2002.
