Abstract
We consider thermally excited passages and droplets formed between flu id membranes in a lamellar phase. We show that they induce entropic at tractive interactions which compete with Helfrich's entropic intermemb rane repulsion. This competition determines the intermembrane distance l(max) lamellar phases reach at transitions to isotropic fluid membra ne phases. In general, l(max) is much smaller than the membrane persis tence length and crucially depends on membrane saddle-splay (''Gaussia n'') rigidity.
