REZUMAT: 
This book addresses an important topic of xed point theory, namely that
of xed point theory for cyclic operators (singlevalued and multivalued) dened
on metric spaces, generalized metric spaces or special classes of Banach spaces.
The book also studies the existence of the best proximity points for multivalued
operators of cyclic type. As applications, the coupled xed point problem is
considered and, in particular, a study of the existence of the solution for certain
classes of systems of nonlinear integral equations is performed. Throughout the
book, a special class of cyclic operators is considered, namely those who satisfy
a generalized contraction condition of Ciric type.
