The Cuntz semigroup, a Riesz type interpolation property, comparison and the ideal property
C-algebra the Cuntz semigroup a Riesz type interpolation property
2011/2/25
We define a Riesz type interpolation property for the Cuntz semigroup of a C-algebra and prove it is satisfied by the Cuntz semigroup of every C-algebra with the ideal property. Related to this, we ...
Leaves and trajectories for schemes. Application to the comparison of three classical sheaves over the differential spectrum
Leaves trajectories schemes classical sheaves the differential spectrum
2010/11/15
We define leaves and trajectories for schemes endowed with a vector field. With the help of these tools, we are able to give a geometrical interpretation and to generalize several results and constru...
Generalized Inverse Estimator and comparison with Least Squares Estimator
Inverse Estimator Least Squares Estimator

Trenkler [13] described an iteration estimator. This estimator is defined as follows: for 0 < g < 1/li \max \[ \hat{b}m, g = g \summi=0 (1-g X'X)i X'y , \] where li are eigenvalues of X'X. In this pap...
COMPARISON OF INVARIANTS FOR TRIPLES OF HILBERT SPACES
COMPARISON OF INVARIANTS HILBERT SPACES
2010/3/17
In [2,3] the sequence of invariant characteristics (mm) for the finite families of Hilbert spaces were considered. Here we make a comparison of these invariants among themselves. We construct some exa...
