Let F2,m(C) denote the Fock-Sobolev space of complex plane. In this paper, we characterize semi-commutator two Toeplitz operators on is zero. The result different from Bauer et al. (2015) [2].

With the growing precision of data for light– cone dominated hard scattering processes like DIS, DVCS and various (semi) exclusive processes a better perturbative understanding of QCD concerning higher twist contributions is required. Thereby the nonlocal light–cone expansion (LCE) is optimally adapted since the same nonlocal LC operator, and its anomalous dimension, are related to different ph...

Let A be a positive (semidefinite) bounded linear operator on complex Hilbert space $$\big ({\mathcal {H}}, \langle \cdot , \rangle \big )$$ ( H ? · ? ) . The semi-inner product induced by is defined $${\langle x, y\rangle }_A := Ax, $$ x y : = for all $$x, y\in {\mathcal {H}}$$ ? and defines seminorm $${\Vert \Vert }_A$$ ? $${\mathcal This makes into semi-Hilbert space. For $$p\in [1,+\infty p...
