ACTIUNI, COACTIUNI SI GRADUARI PE ALGEBRE

COD IDEI 1904, contract nr. 479/13.01.2009

Descriere succinta a proiectului de cercetare

Conceptul de graduare isi are originea in teoria polinoamelor si este un instrument important de studiu in teoria reprezentarilor de grupuri, algebra comutativa, geometrie algebrica, comologie, algebre Lie, geometrie diferentiala si fizica teoretica. Cum o G-graduare a unei k-algebre este exact o structura de k[G]-comodul algebra, graduarile sunt cazuri speciale de coactiuni. Proiectul abordeaza, din punct de vedere al graduarii, mai multe directii actuale de cercetare din algebra necomutativa: algebre semisimple, algebre envelopante universale, algebre envelopante cuantice, actiuni si coactiuni pentru algebre de tip Hopf, algebre de (quasi)matrice, algebre de polinoame. Pe scurt, obiectivele stiintifice principale ale proiectului sunt:
1.Studiul graduarilor pe algebre semisimple dupa grupuri.
2.Studiul graduarilor pe algebre de matrice dupa semigrupuri.
3.Studiul graduarilor algebrei de polinoame dupa un grup.
4.Obtinerea de graduari dupa un grup pe algebre universale envelopante si pe algebre envelopante cuantice.
5.Un studiu al coactiunilor unor grupuri cuantice pe anumite clase de algebre.
6.Caracterizarea categoriilor definite de actiuni si coactiuni ale unor (co)algebre graduate de tip Hopf ca si categorii de module graduate dupa un grup, peste o algebra graduata de tip produs smash.
7.Initierea unei teorii de tip Hopf-Galois pentru (co)algebre graduate de tip Hopf.
8.Obtinerea de structuri de quasialgebra graduata pe diverse inele de matrice.
