Diederich-Fornaess index and Steinness index.

- Place: GAIA Seminar Room (#106, Mathematical Science bldg.)

- Date: 8 p.m. - 10 p.m on Monday, 22 January 2018

- SpeakerMr. Jihun Yum (POSTECH)


- Abstract: 

Let D be a bounded pseudoconvex domain in ^n with smooth boundary. Diederich-Fornaess index DF(D) is η1 iff for all η (0, η1), there exists a defining function ρ such that -(-ρ)^η is strictly plurisubharmonic on D. Steinness index S(D) is η2 iff for all η > η2, there exist a defining function ρ and a neighborhood U of ∂D such that ρ^η is strictly plurisubharmonic on (closure{D})^c ∩ U.

We will see the relation between Diederich-Fornaess index and Steinness index on smooth Worm domains.
