WebMar 3, 2024 · In this article, we consider minimal integrals on sublevel sets of a plurisubharmonic function with respect to a module at a boundary point of the sublevel sets, and establish a concavity property of the minimal integrals. As applications, we obtain a sharp effectiveness result related to a conjecture posed by Jonsson-Mustaţă, which … WebAbout Transcript Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ -3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint.

WebNov 16, 2024 · A region in R2 R 2 is called closed if it includes its boundary. A region is called open if it doesn’t include any of its boundary points. A region in R2 R 2 is called bounded if it can be completely contained in a disk. In other words, a region will be bounded if it is finite. Let’s think a little more about the definition of closed. Webthe other hand, when viewed as a subset of R, every element of the set is a boundary point. Theorem: A set A ⊂ X is closed in X iff A contains all of its boundary points. Note the difference between a boundary point and an accumulation point. Take the set A = {0} ⊂ R. 0 is a boundary point of A but not an accumulation point. On the other
