Sur Quelques Limitations des Algorithmes Dans Le Traitement des Suites

— A relation (I.F.) is given which partially expresses the conditions to be satisfied by a séquence transformation in order to be "calculable". We can apply this relation on gênerai space and without using recursive notions. This relation gives us sharp négative results concerning séquence transformations. This is shownfor decidability problems of periodicity,for extraction problems of converge...

Quelques remarques concernant la théorie des corps ordonnés différentiellement clos

We first propose a “geometrical” axiomatization for the theory of closed ordered differential fields (denoted CODF) introduced by M.Singer in 1978 (see [Si]). This axiomatization is the analogue of the Pierce-Pillay axiomatization for the theory of differentially closed fields of characteristic zero (see [PP]). We also remark that a differential lifting principle can be used to prove that CODF ...
