Dimension-raising Homomorphisms between Lattices of Convex Bodies
Luisa Allgaier, Heinz Weisshaupt
We settle the first unsolved case of a problem of P. M. Gruber, asked by him in 1991, namely, to investigate the homomorphisms from the lattice of convex bodies of …

Sensitivity analysis of one parameter semigroups exemplified by the Wright--Fisher diffusion
Peter Pfaffelhuber, Heinz Weisshaupt
We consider the sensitivity, with respect to a parameter θ, of parametric families of operators A_θ, vectors π_θ corresponding to the adjoints A_θ^{*} of A_θ via A_θ^{*}π_θ=0 and o…

The tree length of an evolving coalescent
Peter Pfaffelhuber, Anton Wakolbinger, Heinz Weisshaupt
A well-established model for the genealogy of a large population in equilibrium is Kingman's coalescent. For the population together with its genealogy evolving in time, this gives…
