We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Spectral stability of post-fertilization traveling waves
Gilberto Flores and Ramón G. Plaza
Abstract
This paper studies the stability of a family of post-fertilization traveling waves on eggs proposed by Lane et. al, consisting of an elastic deformation pulse on the egg's surface, and a calcium concentration profile. The family is indexed by a coupling parameter $\epsilon > 0$ that measures the contraction stress effects on the egg's surface. It is shown that the corresponding family of Evans functions for $\epsilon>0$ converges uniformly to the non-vanishing Evans function of the decoupled waves when $\epsilon = 0$, proving spectral stability.
