A computer-assisted proof of Krzyż's conjecture for the sixth coefficient
Frank Wikström
We prove Krzyż's conjecture for the sixth coefficient. Every holomorphic function from the unit disk to the punctured disk satisfies . Equality ho…
The sharp radius in Korenblum's maximum principle for the Fock space
Frank Wikström
Korenblum's maximum principle states that if near the boundary, then . The optimal size of the region of domination has been studied in Bergman s…
A computer-assisted lower bound for Landau's constant
Frank Wikström
We prove the lower bounds \[ B_\infty>0.51,\qquad L>0.51, \] where is the locally univalent Bloch constant and is Landau's constant, improving the bound $\frac{1}{2}…
An improved lower bound for Bloch's constant
Frank Wikström
Let denote Bloch's constant. We prove \[ B \ge \frac{\sqrt{3}}{4}+0.0153 = 0.448312701\ldots, \] improving the lower bounds by Chen--Gauthier () and X…
Perron envelopes with globally bounded minorants
Frank Wikström
Let be an upper semicontinuous function on a domain , and let be the Perron envelope of formed only with subharmonic minorants that are bounded above on all of .…
Moment duality and an improved lower bound for Korenblum's constant
Frank Wikström
We introduce a moment-duality method for Korenblum's maximum principle in the Bergman space . Starting from an annular coefficient estimate of Wang, we show that a…
Jensen Deficits for Inhomogeneous Monge-Ampère Dirichlet Problems
Frank Wikström
We develop an inhomogeneous form of Edwards' Jensen-measure duality for Perron envelopes constrained by Monge--Ampère lower bounds. The admissible subsolution families are convex b…
