Unifying the theory of Integration within normal-, Weyl- and antinormal-ordering of operators and the s--ordered operator expansion formula of density operators [PDF]
, 2009 By introducing the s-parameterized generalized Wigner operator into phase-space quantum mechanics we invent the technique of integration within s-ordered product of operators (which considers normal ordered, antinormally ordered and Weyl ordered product of operators as its special cases). The s-ordered operator expansion formula of density operators is

Properties of Certain Integral Operators [PDF]
Southeast Asian Bulletin of Mathematics, 1989 Two integral operators P a and Q a for analytic functions in the open unit disk are introduced. The object of the present paper is to derive some properties of integral operators P a and Q a .

FEBS Letters, EarlyView.Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

Moment problems for operator polynomials
, 2012 We extend Haviland's theorem on the integral representation of positive linear functionals on usual (real multivariate) polynomials to the integral representation of positive linear maps on operator polynomials mapping into the space of operators.

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Norm Inequalities for Integral Operators on Cones [PDF]
arXiv, 2022 In this dissertation we explore the $[L^{\mathrm{p}},\ L^{q}]$-boundedness of certain integral operators on weighted spaces on cones in ${\mathbb R}^{n}.$ These integral operators are of the type $\displaystyle \int_{V}k(x,\ y)f(y)dy$ defined on a homogeneous cone $V$. The results of this dissertation are then applied to an important class of operators

On Determinants of Integrable Operators with Shifts [PDF]
International Mathematics Research Notices, 2013 Integrable integral operator can be studied by means of a matrix Riemann--Hilbert problem. However, in the case of so-called integrable operators with shifts, the associated Riemann--Hilbert problem becomes operator valued and this complicates strongly the analysis.

The univalence of an integral operator [PDF]
Bulletin of the Transilvania University of Brasov. Series III: Mathematics and Computer Science, 2020 In this paper, we define an integral operator for analytic functions in the open unit disk and we determine the univalence criteria of this integral operator.
