Recursion and decidabilityrst considered and we prove that it coincides with the class of functions computable by a Turing machine. Other characterizations are given: . and functions represented by a term of the .. What is fundamental is that all these different definitions are equivalent, as they characterize the same class

Complexity: time and space difficult than another one and to understand why certain problems are inherently difficult. Two classical measures are introduced: ., which measures the number of elementary steps necessary in an algorithm and ., which measures the size of the memory used. These two measures are asymptotic function

First-order definabilityheory which can be used to decide if a given property is defined by a first-order formula. The aim of this chapter is to show . is a useful framework for expressing .. Classical structures are infinite, but we can also consider classes of finite structures such as graphs or relational structures. In

Models of parallel computationspter, a polynomial number of transitions are followed per unit of time. We consider two models: boolean circuits and the . (Parallel Random Access Machine), although there are many other possible models. Both circuits and PRAM assume synchronized elements which realize concurrent operations. Other m

Definability of optimization and counting problemsn problem associated with them is of the form: Given a threshold value ., decide if there is a solution of size greater than . in the case of a maximization problem and smaller than . in the case of a minimization problem.
