Exponential integral representations of theta functions
Andrew Bakan, Håkan Hedenmalm
Let be the standard Jacobi theta function, which is holomorphic and zero-free in the upper half-plane , and takes po…
Coulomb gas ensembles and Laplacian growth
Haakan Hedenmalm, Nikolai Makarov
We consider the normal matrix ensemble under a general confining potential. We find that the eigenvalues condensate on a compact set in the plane, which we call the spectral drople…
The Beurling operator for the hyperbolic plane
H. Hedenmalm
We find a Beurling operator for the hyperbolic plane, and obtain an norm identity for it, as well as estimates.
Berezin transform in polynomial Bergman spaces
Yacin Ameur, Haakan Hedenmalm, Nikolai Makarov
We study the reproducing kernel for weighted polynomial Bergman spaces and consider applications to the Berezin transform. Some of our results have applications in random matrix th…
On the asymptotic free boundary for the American put option problem
H. Hedenmalm
In practical work with American put options, it is important to be able to know when to exercise the option, and when not to do so. In computer simulation based on the standard the…
Branch point area methods in conformal mapping
Haakan Hedenmalm, Natalia Abuzyarova
The classical estimate of Bieberbach -- that for a given univalent function in the class -- leads to best possible pointwise estimates of the ra…
