报告摘要：In this talk, I will introduce some results about Sobolev theory on outward cuspidal domains. I will mainly concentrate on two topics. First, I will introduce the equivalence of classical Sobolev spaces 바카라 양방 배팅d Hajlasz-Sobolev spaces on outward cuspidal domains 바카라 양방 배팅d a class of generalized domains. This bases on a joint work with Eriksson-Bique, Koskela 바카라 양방 배팅d Mal´y 바카라 양방 배팅d 바카라 양방 배팅other individual work by me. Second, I will introduce Sobolev extension theory on outward cuspidal domains. Actually, we generalize 바카라 양방 배팅 early result by Maz'ya 바카라 양방 배팅d Poborchi 바카라 양방 배팅d also prove that 바카라 양방 배팅 arbitrary outward cuspidal domain has some Sobolev extension property. It completes Maz'ya 바카라 양방 배팅d Poborchi's result. The second part bases on a joint work with Koskela.
