A 3-local identification of the alternating group of degree 8, the McLaughlin simple group and their automorphism groups

[OWP-2007-02] Parker, Christopher; Rowley, Peter (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-20)

In this article we give 3-local characterizations of the alternating and symmetric groups of degree 8 and use these characterizations to recognize the sporadic simple group discovered by McLaughlin from its 3-local subgroups.

Slowly oscillating wave solutions of a single species reaction-diffusion equation with delay

[OWP-2007-12] Trofimchuk, Elena; Tkachenko, Victor; Trofimchuk, Sergei I. (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-28)

We study positive bounded wave solutions

$u(t, x) = \phi(\nu \cdot x+ct)$ ,

$\phi(-\infty)=0$ , of equation

$u_t(t, x)=\delta u(t,x)−u(t,x) +g(u(t−h,x))$ ,

$x \in \mathbb{R}^m$ (*). It is supposed that Eq. (∗) has exactly two ...
