(Schroder [62]). In Chapter III we discuss the results related to commuting functions and common fixed points. We also present some new results on commuting

In terminology of [16] Theorem 4.3 implies that the alternation-depth hierarchy of fixed-point expressions collapses for lattices D with co-continuous "U" and dis-

In this section we show that λβ satisfies the open fixed point property. More precisely, we show that every λ-term exhibiting a non-constant behaviour has infinitely many

En revanche, si l’on se réfère aux distances longitudinales et verticales entre le centre du volant et le point de référence du siège, on constate que plus la hauteur d’assise

The iterative Lloyd’s algorithm [12] is used in our case study. It is applied to bidimensional sets of vectors in order to have easier display and interpretation of the results.

We also focus on spaces of open sets, on which one can take advantage of the lattice structure to give a very neat characterization of the fixed-point property and again prove

Douady gave examples in [D88] of Lyapunov unstable elliptic points for smooth symplectic diffeomor- phisms for any n ě 2, for which the Birkhoff normal form has non- degenerate

It is a consequence of existing literature that least and greatest fixed-points of monotone polynomials on Heyting algebras—that is, the alge- braic models of the
