Descriere succinta a proiectului de cercetare

Studiem cateva probleme de interes curent in teoria algebrelor hopf, legate de produse incrucisate, algebre hopf punctate, si teoria reprezentarii algebrelor hopf si generalizari. Vizam de asemenea sa extindem si sa studiem metode categoricale in algebre hopf, cum ar fi categorii monoidale, braided si tensoriale, si sa examinam cateva probleme generale categoricale legate de aceastea.
