On the differential and Volterra-type integral operators on Fock-type spaces [PDF]

open access: yes, 2022
The differential operator fails to admit some basic structures including continuity when it acts on the classical Fock spaces or weighted Fock spaces, where the weight functions grow faster than the classical Gaussian weight function. The same conclusion

A matrix acting between Fock spaces

open access: yesJournal of Inequalities and Applications
If H ν = ( ν n , k ) n , k ≥ 0 $\mathcal{H}_{\nu}=(\nu _{n,k})_{n,k\geq 0}$ is the matrix with entries ν n , k = ∫ [ 0 , ∞ ) t n + k n ! d ν ( t ) $\nu _{n,k}=\int _{[0,\infty )}\frac{ t^{n+k}}{n!}\,d\nu (t)$ , where ν is a nonnegative Borel measure on ...

On the product of Toeplitz and composition operators on Fock-Sobolev spaces

open access: yes四川大学学报. 自然科学版, 2021
We characterize the boundedness of the product of Toeplitz and composition operators for two polynomials symbols on Fock-Sobolev spaces. We also consider the commutativity of Toeplitz and composition operator, and obtain several necessary and sufficient ...

Quasi-isomorphisms of cluster algebras and the combinatorics of webs (extended abstract) [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
We provide bijections between the cluster variables (and clusters) in two families of cluster algebras which have received considerable attention. These cluster algebras are the ones associated with certain Grassmannians of k-planes, and those associated

Polynomial Representations and Categorifications of Fock Space [PDF]

open access: yesAlgebras and Representation Theory, 2012
The rings of symmetric polynomials form an inverse system whose limit, the ring of symmetric functions, is the model for the bosonic Fock space representation of the affine Lie algebra. We categorify this construction by considering an inverse limit of categories of polynomial representation of general linear groups.

Deep Learning–Based Extraction of Promising Material Groups and Common Features from High‐Dimensional Data: A Case of Optical Spectra of Inorganic Crystals

open access: yesAdvanced Intelligent Discovery, EarlyView.
We report a novel interpretation method for deep learning models based on feature extraction and clustering. Applying this method to an atomistic line graph neural network (ALIGNN) model trained on optical absorption spectra of 2,681 inorganic compounds obtained from first‐principles calculations, we successfully identify key factors underlying ...

Theoretical prediction of superatom molecular orbitals (SAMOs) in the ice-like cluster (H2O)10 and its impact in the supramolecular chemistry and function of nanostructured water

open access: yesChemical Physics Impact, 2022
Superatom molecular orbitals (SAMOs) are atom-like molecular orbitals that have been observed in the buckminsterfullerene C60 molecule. We studied the ice-like water cluster (H2O)10 that is expected to be ubiquitous in nature in nanoscale ...

Squeezed‐Vacuum Bosonic Codes

open access: yesAdvanced Physics Research, EarlyView.
ABSTRACT We introduce a family of bosonic quantum error‐correcting codes built as a rotation‐symmetric superposition of squeezed vacuum states, which promise protection against both loss and dephasing noise channels. The robustness of these “squeezed‐vacuum codes” arises from being arranged at evenly spaced angles in phase‐space, and simultaneously in ...

SO2 Transfer Enabled by an Easy‐to‐Handle Ionic Liquid

open access: yesChemistry – A European Journal, EarlyView.
Best of both worlds: The ionic liquid [NEt3Me][Cl(SO2)n] unites the atom economy and low cost of sulfur dioxide with the safety and applicability of common surrogates, streamlining SO2 transfer to access to 3‐sulfolenes, sulfonamides, and SuFEx reagents.

Boundedness and Compactness Of Generalized Integration Operators on Fock Spaces [PDF]

open access: yes, 2022
Different properties of Volterra-type integral operator have been studied in the past two decades on several functional spaces. In particular, on Fock spaces boundedness and compactness of the operator was studied by (Constantin, 2012) and (Mengestie ...
