Sixtieth birthday of Professor Karel Rektorys

In honor of the sixtieth birthday of

1 Introduction This paper is written to commemorate the sixtieth birthday of Paul Garabedian. While Paul has made broad ranging contributions in mathematics, fluid dynamics and plasma physics, his work on computational aerodynamics had a very forceful impact at a critical juncture in the development of this subject. I believe that this work should be regarded as being very much in the tradition...

Niemeier Lattices and K3 Groups Dedicated to Professor I. Dolgachev on the Occassion of His Sixtieth Birthday

In this note, we consider K3 surfaces X with an action by the alternating group A 5. We show that if a cyclic extension A 5 .C n acts on X then n = 1, 2, or 4. We also determine the A 5-invariant sublattice of the K3 lattice and its discriminant form.

A celebration of Horst Seidler on his sixtieth birthday.

Horst Seidler’s curriculum vitae reminds the anthropologist of the early descriptions of human evolution, or, better, it is like the classic »hero myth«. The brave warrior sets out on his journey, seeks and faces and masters challenges along the way, and triumphs at the end. The heroic saga is a parable for Seidler’s scientific career that touches on several aspects of his personality: a deep e...

CONFLUENCE PROCESSES IN DEFINING MANIFOLDS FOR PAINLEVE SYSTEMS Dedicated to Professor Norio Shimakura on his sixtieth birthday

For each Painlevé system, we have a manifold, called the defining manifold, on which the system defines a uniform foliation. In this paper, we describe confluence processes in these manifolds as deformations of manifolds compatible to those in Painlevé systems.
