L 2 extension of adjoint line bundle sections

Dano Kim (2010)

Annales de l’institut Fourier

Similarity:

We prove an extension theorem of Ohsawa-Takegoshi type for line bundle sections on a subvariety of general codimension in a normal projective variety. Our method of proof gives conditions to be satisfied for such extension in a general setting, while such conditions are satisfied when the subvariety is given by an appropriate multiplier ideal sheaf.

Normalization of bundle holomorphic contractions and applications to dynamics

François Berteloot, Christophe Dupont, Laura Molino (2008)

Annales de l’institut Fourier

Similarity:

We establish a Poincaré-Dulac theorem for sequences ( G n ) n of holomorphic contractions whose differentials d 0 G n split regularly. The resonant relations determining the normal forms hold on the moduli of the exponential rates of contraction. Our results are actually stated in the framework of bundle maps. Such sequences of holomorphic contractions appear naturally as iterated inverse branches of endomorphisms of k . In this context, our normalization result allows to estimate precisely...

Natural transformations between T²₁T*M and T*T²₁M

Miroslav Doupovec (1991)

Annales Polonici Mathematici

Similarity:

We determine all natural transformations T²₁T*→ T*T²₁ where T k r M = J 0 r ( k , M ) . We also give a geometric characterization of the canonical isomorphism ψ₂ defined by Cantrijn et al.
