Resolution of symplectic cyclic orbifold singularities
[OWP-2007-03] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-21)In this paper we present a method to obtain resolutions of symplectic orbifolds arising as quotients of pre-symplectic semi-free S1-actions. This includes, in particular, all orbifolds arising from symplectic reduction of ... -
Secondary heat flow between confocal ellipses: an application of extended thermodynamics
[OWP-2007-11] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-27)Much as non-Newtonian fluids exhibit secondary flows in elliptic pipes, rarefied gases exhibit secondary heat flows between elliptical cylinders. The phenomenon may be called non-Fourierian, because it is not covered by ... -
Self-dual polygons and self-dual curves

Slowly oscillating wave solutions of a single species reaction-diffusion equation with delay
[OWP-2007-12] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-28)We study positive bounded wave solutions u(t,x)=ϕ(ν⋅x+ct), ϕ(−∞)=0, of equation ut(t,x)=δu(t,x)−u(t,x)+g(u(t−h,x)), x∈Rm(*). It is supposed that Eq. (∗) has exactly two ... -
Vector bundles on degenerations of elliptic curves and Yang-Baxter equations
[OWP-2007-04] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-22)In this paper we introduce the notion of a gemetric associative r-matrix attached to a genus one fibration with a section and irreducible fibres. It allows us to study degenerations of solutions of the classical Yang-Baxter ... -
Zeta functions of 3-dimensional p-adic Lie algebras
[OWP-2007-10] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-26)We give an explicit formula for the subalgebra zeta function of a general 3-dimensional Lie algebra over the p-adic integers Zp. To this end, we associate to such a Lie algebra a ternary quadratic form over ...
