Reinhardt Domains with a Cusp at the Origin
نویسنده
چکیده
Let Ω be a bounded pseudoconvex Reinhardt domain in C with many strictly pseudoconvex points and logarithmic image ω. It was known that the maximal ideal in H∞(Ω) consisting of all functions vanishing at (p1, p2) ∈ Ω is generated by the coordinate functions z1 − p1, z2 − p2 (meaning that one can solve the Gleason problem for H∞(Ω)) if ω is bounded. We show that one can solve Gleason’s problem for H∞(Ω) as well if there are positive numbers a, b and a positive rational number k l such that Ω looks like {(z1, z2) ∈ C : a|z2| ≤ |z1| ≤ b|z2|} for small z.

Let$mathbb{C}^n$ be the space of $n$ complex variables. Let$Omega_{n,p_2,ldots,p_n}$ be a complete Reinhardt on$mathbb{C}^n$. The Minkowski functional on complete Reinhardt$Omega_{n,p_2,ldots,p_n}$ is denoted by $rho(z)$. The concept ofspirallike mapping of type $beta$ and order $alpha$ is defined.So, the concept of the strong and almost spirallike mappings o...
متن کاملSymmetric continuous Reinhardt domains
whenever |ζ1|, . . . , |ζn| ≤ 1 . In 1974 [11] Sunada investigated the structure of bounded Reinhardt domains containing the origin from the viewpoint of biholomorphic equivalence. He was able to describe completely the symmetric Reihardt domains which, up to linear isomomorphism, turned to be direct products of Euclidean balls. Our aim in this paper is to study infinite dimensional analogs of ...
متن کاملComparative Evaluation of Fracture Strength of Cusp Coverage with Composite Versus Unsupported Enamel Reinforced with Composite in Posterior Dental Restorations
Background and aim: Efficient bonding techniques should be employed for strengthening tooth structure. Whether to preserve intact dental tissue or to sacrifice some undermined parts can still be challenging. We aimed to evaluate the fracture strength of cusp coverage with composite versus unsupported enamel reinforced with composite in posterior restorations. Materials and methods: In this in...
متن کاملMandibular Talon Cusp Associated With Molar-Incisor Hypomineralization and Delayed Tooth Eruption
Talon cusp is an odontogenic anomaly in anterior teeth, caused by hyperactivity of enamel in morphodifferentiation stage. Talon cusp is an additional cusp with several types based on its extension and shape. It has enamel, dentin, and sometimes pulp tissue. Moreover, it can cause clinical problems such as poor aesthetic, dental caries, attrition, occlusal interferences, and periodontal di...
