    Fibrations structures and degree formulae for Milnor fibers.
    (2015) Dutertre, N.; Santos, Raimundo Nonato Araújo dos; Chen, Y.; Andrade, A.
    In this survey, we remind some fibrations structure theorems (also called Milnor’s fibrations) recently proved in the real and complex case, in the local and global settings.

    Open book structures on semi-algebraic manifolds.
    (2015) Dutertre, N.; Santos, Raimundo Araujo dos; Andrade, A.; Chen, Y.
    Given a C2 semi-algebraic mapping F : R N → Rp , we consider its restriction to W ,→ R N an embedded closed semi-algebraic manifold of dimension n − 1 ≥ p ≥ 2 and introduce sufficient conditions for the existence of a fibration structure (generalized open book structure) induced by the projection FkF k : W \F −1 (0) → S p−1.
