A generalization of the Nikodym boundedness theorem.

Christopher Stuart (2007)

Collectanea Mathematica

Similarity:

In this note an internal property of a ring of sets, named the Nested Partition Property, is shown to imply the Nikodym Property. A wide range of examples are shown to have this property.

Francisco J. Plaza Martín (2005)

Collectanea Mathematica

Similarity:

An explicit basis of the space of global vector fields on the Sato Grassmannian is computed and the vanishing of the first cohomology group of the sheaf of derivations is shown.
