바카라 양방 배팅摘要： In this talk, we discuss the Nakayama automorphism 바카라 양방 배팅 a PBW-deformation 바카라 양방 배팅 a Koszul Artin-Schelter Gorenstein algebra 바카라 양방 배팅 finite global dimension. A criterion for an augmented PBW-deformation 바카라 양방 배팅 Koszul Calabi-Yau algebra to be still Calabi-Yau will be given. The relations 바카라 양방 배팅 the Calabi-Yau property 바카라 양방 배팅 augmented PBW-deformations and that 바카라 양방 배팅 non-augmented cases are discussed. The Nakayama automorphisms 바카라 양방 배팅 PBW-deformations 바카라 양방 배팅 Koszul Artin-Schelter Gorenstein algebras 바카라 양방 배팅 global dimensions 2 and 3 are given explicitly. It is proved that if a PBW-deformation 바카라 양방 배팅 a graded Calabi-Yau algebra is still Calabi-Yau, then it is defined by a potential under some mild conditions. Some classical results are also recovered.
