DESCRIPTION:In 1966 Grätzer introduced the notion 
 of transferability for finite lattices. A finite l
 attice L is transferable if whenever L has an embe
 dding into the ideal completion of a lattice K, th
 en L already has an embedding into K. In this talk
  we will introduce the analogous notion of MacNeil
 le transferability, replacing the ideal completion
  with the MacNeille completion. We will pay partic
 ular attention to MacNeille transferability of fin
 ite distributive lattices with respect to the clas
 s of Heyting algebras. This will also allow us to 
 find universal classes of Heyting algebras closed 
 under MacNeille completions.  This is joint work w
 ith G. Bezhanishvili, J. Harding, and J. Ilin.
