On norm closed ideals in L(\ell_p\oplus\ell_q)

B. Sari, Th. Schlumprecht, N. Tomczak-Jaegermann +1

It is well known that the only proper non-trivial norm-closed ideal in the algebra L(X) for X=\ell_p (1 \le p < \infty) or X=c_0 is the ideal of compact operators. The next natural…

Reconstruction and subgaussian operators

Shahar Mendelson, Alain Pajor, Nicole Tomczak-Jaegermann

We present a randomized method to approximate any vector $v$ from some set $T \subset R^{n}$ . The data one is given is the set $T$ , and $k$ scalar products $(\inr{X_i,v})_{i=1}^k$,…
