SUMMARY: (...): V. Paternostro (TU Berlin): Fibers as a tool to characteriz
 e frames of translates
DESCRIPTION:: Fibers as a tool to characterize frames of translates by Vict
 oria Paternostro (TU Berlin)\n\nIn this talk we will see how to analyze fr
 ame properties on systems of translates using fiberization techniques. We 
 will first discuss the concept of fibers in L_2(R^d) and its relationship 
 with systems of the form {T_kφ : k ∈ Z^d\\\, φ ∈ A} where A is a set
  of functions of L2(R^d) and T_k is the shift operator by k. We will then 
 see how this notion can be defined in more general contexts than L_2(R^d).
  Mainly\\\, we will work with fibers designed to deal with systems in Hilb
 ert spaces generated by the action of a discrete group. We will provide se
 veral examples to illustrate the theory. \nThe results we present in this 
 talk are in collaboration with D. Barbieri\\\, C. Cabrelli and Eugenio Her
 nandez.
