Toeplitz Operators with IMOs Symbols between Generalized Fock Spaces

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
In this paper, we study the mapping properties of Toeplitz operators Tf associated with IMOs symbols f acting between two generalized Fock spaces Fφp, where 1 < s ≤ ∞. We characterize bounded or compact Toeplitz operators Tf from one generalized Fock space Fφp to another Fφq, respectively, in four cases.

Heat and Laplace type equations with complex spatial variables in weighted Fock spaces

Electronic Journal of Differential Equations, 2020
In a recent book co-authored by the authors of this article, we studied by semigroup theory methods several classical evolution equations, including the heat and Laplace equations, with real time variable and complex spatial variable, under the ...

New Inequalities and an Integral Expression for the 𝒜‐Berezin Number

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This work examines a reproducing kernel Hilbert space XF,·,· constructed on a nonempty set F. Our investigation focuses on the A‐Berezin number and the A‐Berezin norm, where A denotes a positive bounded linear operator acting on XF. For an A‐bounded linear operator B, the A‐Berezin seminorm is defined by BberA=supλ,ν∈FBu∧λ,u∧νA, where u∧λ and u∧ν are ...

Arithmetic progressions and holomorphic phase retrieval

Bulletin of the London Mathematical Society, Volume 56, Issue 11, Page 3316-3330, November 2024.
Abstract We study the determination of a holomorphic function from its absolute value. Given a parameter θ∈R$\theta \in \mathbb {R}$, we derive the following characterization of uniqueness in terms of rigidity of a set Λ⊆R$\Lambda \subseteq \mathbb {R}$: if F$\mathcal {F}$ is a vector space of entire functions containing all exponentials eξz,ξ∈C∖{0}$e^{

On Haptotropic Rearrangements of Diphosphene and Diarsene Ligands in Titanium Complexes

Chemistry – A European Journal, Volume 30, Issue 25, May 2, 2024.
Addition of simple Lewis basic ligands L, such as MeCN or CO among others, results in a shift of the hapticity of the dipnictene ligand in titanocene dipnictene complexes Cp2Ti(Pn2R2) (Pn=P, As) from η2 to η1. While the starting complexes are TiIV species the η1 complexes are best described as singlet biradicals with antiferromagnetically coupled ...

Computational Modelling and Mechanistic Insight into Light‐Driven CO Dissociation of Square‐Planar Rhodium(I) Complexes

ChemPhotoChem, Volume 8, Issue 5, May 2024.
C−H activation: Rh‐phosphine complexes can activate C−H bonds in otherwise unreactive alkanes. Quantum chemical calculations provide mechanistic insights into the generation of the active species which is formed via the light‐induced CO dissociation at Rh(I) complexes featuring trimethylphosphine and 1,2‐bis(dimethylphosphino)ethane.

An extension of the complex–real (C–R) calculus to the bicomplex setting, with applications

Mathematische Nachrichten, Volume 297, Issue 2, Page 454-481, February 2024.
Abstract In this paper, we extend notions of complex C−R$\mathbb {C} - \mathbb {R}$‐calculus to the bicomplex setting and compare the bicomplex polyanalytic function theory to the classical complex case. Applications of this theory include two bicomplex least mean square algorithms, which extend classical real and complex least mean square algorithms.
