DESCRIPTION:Tight knots and links arising in the infrared limit of string 
 theories may provide an interesting alternative to flavor symmetries for e
 xplaining the observed flavor patterns in the leptonic sector. As an examp
 le we consider a type I seesaw model where the Majorana mass structure is 
 based on the discrete length spectrum of tight knots and links. It is show
 n that such a model is able to provide an excellent fit to current neutrin
 o data and that it predicts a normal neutrino mass hierarchy as well as a 
 small mixing angle $	heta_{13}$.\n\n
