Hodge-Bott-Chern decompositions of mixed type forms on foliated Kähler manifolds

Cristian Ida (2014)

Colloquium Mathematicae

The Bott-Chern cohomology groups and the Bott-Chern Laplacian on differential forms of mixed type on a compact foliated Kähler manifold are defined and studied. Also, a Hodge decomposition theorem of Bott-Chern type for differential forms of mixed type is proved. Finally, the case of projectivized tangent bundle of a complex Finsler manifold is discussed.

Holomorphic extension maps for spaces of Whitney jets.

Jean Schmets, Manuel Valdivia (2001)

RACSAM

The key result (Theorem 1) provides the existence of a holomorphic approximation map for some space of C∞-functions on an open subset of Rn. This leads to results about the existence of a continuous linear extension map from the space of the Whitney jets on a closed subset F of Rn into a space of holomorphic functions on an open subset D of Cn such that D ∩ Rn = RnF.

Holomorphic non-holonomic differential systems on complex manifolds

S. Dimiev (1991)

Annales Polonici Mathematici

We study coherent subsheaves 𝓓 of the holomorphic tangent sheaf of a complex manifold. A description of the corresponding 𝓓-stable ideals and their closed complex subspaces is sketched. Our study of non-holonomicity is based on the Noetherian property of coherent analytic sheaves. This is inspired by the paper [3] which is related with some problems of mechanics.

Homologie des ensembles semi-pfaffiens

Jean-Marie Lion, Jean-Philippe Rolin (1996)

Annales de l'institut Fourier

Un sous-ensemble pfaffien d’un ouvert semi-analytique M R n est une intersection finie d’ensembles semi-analytiques relativement compacts de R n et de feuilles non spiralantes de certains feuilletages analytiques de codimension 1 de M . Les sous-ensembles semi-pfaffiens de M sont les éléments de la plus petite classe de sous-ensembles de M contenant les sous-ensembles pfaffiens de M , stable par intersection finie, réunion finie et différence symétrique. Les ensembles T -pfaffiens sont les éléments de la...
