Automatic selfadjoint-ideal semigroups for finite matrices
Sasmita Patnaik, Sanehlata, Gary Weiss
The notion of automatic selfadjointness of all ideals in a multiplicative semigroup of the bounded linear operators on a separable Hilbert space B(H) arose in a 2015 discussion wit…

Singly generated Selfadjoint-Ideal operator semigroups: spectral density of the generator and simplicity
Sasmita Patnaik, Sanehlata, Gary Weiss
This extends our new study of the automatic selfadjoint ideal property for B(H)-operator semigroups introduced to us by Heydar Radjavi (SI semigroups for short). Our investigation…
