DESCRIPTION:Speakers: Dr. XENITIDIS\, Pavlos (Liverpool Hope University)\n
 In this talk we introduce a class of systems of difference equations defin
 ed on an elementary quadrilateral of the lattice and derive necessary cond
 itions for their integrability. These conditions follow from the requireme
 nt that the system admits infinite hierarchies of symmetries\, and can be 
 used in the construction of the lowest order symmetries of the system. The
 se considerations are demonstrated with the help of three systems from the
  class under consideration.\n\nhttp://indico.fuw.edu.pl/contributionDispla
