Similarity:

We present necessary and sufficient conditions for a rearrangement invariant function space to have a complete orthonormal uniformly bounded RUC system.

Solvability of invariant sublaplacians on spheres and group contractions

Fulvio Ricci, Jérémie Unterberger (2001)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

Similarity:

In the first part of this paper we study the local and global solvability and the hypoellipticity of a family of left-invariant sublaplacians L α on the spheres S 2 n + 1 U n + 1 / U n . In the second part, we introduce a larger family of left-invariant sublaplacians L α , β on S 3 S U 2 and study the corresponding properties by means of a Lie group contraction to the Heisenberg group.

Algebras of differentiable functions

Eugène Lee (1967)

Annales de l'institut Fourier

Similarity:

Tout espace de fonctions différentiables invariant sous 0 ( n ) est une algèbre de Banach. De Leeuw et Mirkil ( 13, 1963) ont classifié tous ces “rotating spaces” pour n = 2 . Nous obtenons ici des résultats correspondants pour n arbitraire. Une classification analogue est aussi obtenue pour des espaces de fonctions différentiables sur C n invariants sous U ( n ) .

Symmetries of holomorphic geometric structures on tori

Complex Manifolds

Similarity:

We prove that any holomorphic locally homogeneous geometric structure on a complex torus of dimension two, modelled on a complex homogeneous surface, is translation invariant. We conjecture that this result is true in any dimension. In higher dimension, we prove it for G nilpotent. We also prove that for any given complex algebraic homogeneous space (X, G), the translation invariant (X, G)-structures on tori form a union of connected components in the deformation space of (X, G)-structures. ...
