Descriere succinta a proiectului de cercetare

In acest proiect ne propunem sa continuam studiul algebrelor Hopf si al unor structuri algebrice strans legate de acestea, pe urmatoarele directii de cercetare:

  1. Coactiuni ale unor clase de algebre Hopf pe anumite algebre;
  2. Structuri braided monoidale versus bimonade monoidale;
  3. Proprietati omologice ale algebrelor de incidenta;
  4. Produse incrucisate;
  5. Coomologie ciclica pentru algebre;
  6. Structuri combinatorice cu aplicatii la algebre si coalgebre.
