## Abstract

We consider reaction-diffusion equations on a thick curved surface and obtain a set of effective R-D equation to ${\\cal O}(\\epsilon^2)$, where $\\epsilon$ is the surface thickness. We observe that the R-D systems on these curved surfaces can have space- dependent reaction kinetics. Further, we use linear stability analysis to study the Schnakenberg model on spherical and cylindrical geometries. The dependence of steady state on the thickness is determined for both cases, and we find that a change in the thickness can stabilize the unstable patterns, and vice versa. The combined effect of thickness and curvature can play an important role in the rearrangement of spatial patterns on thick curved surfaces.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
