We show that for all k 1 and n 0 the simplicial complexes T (k) n of all leaflabelled trees with nk+2 leaves and all interior vertices of degrees kl+2 (l 1) are shellable. This yields a direct combinatorial proof that they are Cohen Macaulay and that their homotopy types are wedges of spheres.

Singularity Theory is used to comprehensively investigate the bifurcations of the steady states of the traveling wave ODEs of the cubic-quintic Ginzburg-Landau equation (CGLE). These correspond to plane waves of the PDE. In addition to the most general situation, we also derive the degeneracy condit
