Fredholm and Schatten Class Operators on Bergman Spaces with Exponential Weights
In this paper, we give a characterization of Fredholmness of the Toeplitz operators on the Bergman spaces Aφp with exponential weights in D when 0 < p < ∞. Also, we obtain the sufficient and necessary conditions which the Toeplitz and Hankel operators on Aφ2 belong to h‐Schatten class, where h is a continuous increasing convex function.

Some Berezin Number Inequalities for Operator Matrices [PDF]
The Berezin symbol à of an operator A acting on the reproducing kernel Hilbert space $$\mathcal{H}=\mathcal{H}(\Omega)$$H=H(Ω) over some (nonempty) set is defined by $$\tilde A(\lambda ) = \left\langle {A\hat k_\lambda ,\hat k_\lambda } \right\rangle ...

Social movement studies have addressed the issue of nostalgia within two perspectives, focusing, respectively, on emotions and on memory. Our contribution looks at nostalgia in social movements by building upon the combination of these two streams in social movement studies.

Berezin number inequalities in terms of Specht's
Smooth functions are associated with operators on Hilbert spaces of analytic functions through the Berezin transform. The Berezin symbol and the Berezin number of an operator A on the Hilbert functional space H(Ω) over some set Ω with the reproducing ...

Abstract The resazurin (raz)‐resorufin (rru) smart tracer system has led to significant advances in hydrologic and biogeochemical sciences but its application has been limited in scope and geography by the short duration that it has been assumed samples can be reliably stored before analysis.

Na+ homeostasis in Acinetobacter baumannii is facilitated via the activity of the Mrp antiporter
Summary The human opportunistic pathogen Acinetobacter baumannii is a global threat to healthcare institutions worldwide, since it developed very efficient strategies to evade host defence and to adapt to the different environmental conditions of the host. This work focused on the importance of Na+ homeostasis in A.

Boundedness and Compactness of Hankel Operators on Large Fock Space
We introduce the BMO spaces and use them to characterize complex‐valued functions f such that the big Hankel operators Hf and Hf¯ are both bounded or compact from a weighted large Fock space Fp(ϕ) into a weighted Lebesgue space Lp(ϕ) when 1 ≤ p < ∞.

Some results related with Berezin symbols and Toeplitz operators [PDF]
We investigate some problems related with Berezin symbols of operators on Hardy and Bergman spaces and their applications in summability theory and in solution of Beurling problem. We also study boundedness and invertibility of some Toeplitz products on the Hardy and Bergman spaces.

Semi-classical properties of Berezin–Toeplitz operators with Ck-symbol [PDF]
We obtain the semi-classical expansion of the kernels and traces of Toeplitz operators with Ck-symbol on a symplectic manifold. We also give a semi-classical estimate of the distance of a Toeplitz operator to the space of self-adjoint and multiplication ...

Toeplitz Operators with Essentially Radial Symbols
For Topelitz operators with radial symbols on the disk, there are important results that characterize boundedness, compactness, and its relation to the Berezin transform.
