Abstract

A theory is presented showing that local instabilities of composite biological membranes, consisting of a lipid bilayer and an underlying actin cortex, can be triggered by a local softening of the membrane associated cytoskeleton. A function describing the local softening was introduced and a basic equation that has to be solved to determine the local shape instability arising from local softening.
