Higher Rank Numerical Ranges and Unitary Dilations

Pankaj Dey, Mithun Mukherjee

Here we show that for the closure of the -rank numerical range of a contraction acting on an infinite-dimensional Hilbert space is the inters…

Higher Rank Numerical Ranges of Normal Operators and unitary dilations

Pankaj Dey, Mithun Mukherjee

We describe here the higher rank numerical range, as defined by Choi, Kribs and Zyczkowski, of a normal operator on an infinite dimensional Hilbert space in terms of its spectral m…
