WebAbstract. We study linear extremal problems in the Bergman space Ap of the unit disc for p an even integer. Given a functional on the dual space of Ap with representing kernel k ∈ Aq, where 1/p + 1/q = 1, we show that if the Taylor coefficients of k are sufficiently small, then the extremal function F ∈ H∞. We also show that if q ≤ q 1 ... WebExtremal graph theory is the branch of graph theory that studies extremal (maximal or minimal) graphs which satisfy a certain property. Extremality can be taken with respect to di erent graph invariants, such as order, size or girth. For example, a simple extremal graph theory question is "which acyclic graphs on n vertices have the maximum ...

Webextremal transition, a general expectation is that the Gromov-Witten theory of Y can be realized as a sub-theory of the Gromov-Witten theory of X. However, it is not clear what statement one can prove for extremal transitions. 1.3 Extremal Transitions Let Xand Y be two smooth varieties over C. The process of going from Xto Y cpt code books 2015
