An Interesting Class of Operators with unusual Schatten-von Neumann behavior

A. B. Aleksandrov, S. Janson, V. V. Peller +1

We consider the class of integral operators $Q_\f$ on $L^{2} (R_{+})$ of the form $(Q_\f f)(x)=\int_0^\be\f (\max\{x,y\})f(y)dy$. We discuss necessary and sufficient conditions on $ϕ$ …

Noncommutative complex analysis and Bargmann-Segal multipliers

Richard Rochberg, Nik Weaver

We state several equivalent noncommutative versions of the Cauchy-Riemann equations and characterize the unbounded operators on L^2(R) which satisfy them. These operators arise fro…
