| Aims |
|
The aim of this course is to provide basic concepts and tools in fixed point theory and in nonlinear analysis and then to apply this notions and results to the theory of differential and integral equations and to applied functional analysis.

| Content |
|
1. Contraction principle and applications (convergence of the sequences, operatorial equations, Cauchy problem, Dirichlet problerm).
2. Generalizations and extensions of the contraction principle (Kannan@s theorem, Maia@s theorem). 3. Caristi-Browder fixed point theorem, graphic contraction theorem. 4. Picard and weakly Picard operators. Examples. data dependence of the fixed point set. 5. Abstract Gronwall lemma. Comparison theorems. 6. Completely continuous operators in Banach spaces. Examples. 7. Schauder@s theorems and applications in Fredholm and Volterra type equations. 8. Nonexpansive operators in Hilbert spaces. 9. Recent trends in nonlinear analysis. |
