Blind Deconvolution of Seismic Data Using f-Divergences
Entropy, 2011 This paper proposes a new approach to the seismic blind deconvolution problem in the case of band-limited seismic data characterized by low dominant frequency and short data records, based on Csiszár’s f-divergence.

NLO fragmentation functions for a quark into a spin-singlet quarkonium: same flavor case
Journal of High Energy Physics, 2021 In the paper, we calculate the fragmentation functions for c → η c and b → η b up to next-to-leading-order (NLO) QCD accuracy. The ultraviolet divergences in the real corrections are removed through operator renormalization under the modified min- imal ...

Fragmentation functions for gluon into B c or B c ∗ $$ {B}_c^{\ast } $$ meson
Journal of High Energy Physics, 2022 In the paper, we calculate the fragmentation functions for g → B c and g → B c ∗ $$ {B}_c^{\ast } $$ . The ultraviolet divergences in the calculation are removed through the renormalization of the operator definition of the fragmentation functions under ...

Quantum $f$-divergences in von Neumann algebras I. Standard $f$-divergences
, 2018 We make a systematic study of standard $f$-divergences in general von Neumann algebras. An important ingredient of our study is to extend Kosaki's variational expression of the relative entropy to an arbitary standard $f$-divergence, from which most of ...

Non‐commutative ‐divergence functional [PDF]
Mathematische Nachrichten, 2013 We introduce the non‐commutative f‐divergence functional urn:x-wiley:dummy:mana201200194:equation:mana201200194-math-0002for an operator convex function f, where and are continuous fields of Hilbert space operators and study its properties. We establish some relations between the perspective of an operator convex function f and the non‐commutative f‐

Quantum $f$-divergences in von Neumann algebras II. Maximal $f$-divergences
, 2018 As a continuation of the paper [20] on standard $f$-divergences, we make a systematic study of maximal $f$-divergences in general von Neumann algebras. For maximal $f$-divergences, apart from their definition based on Haagerup's $L^1$-space, we present ...

Law invariant risk measures and information divergences
Dependence Modeling, 2018 Aone-to-one correspondence is drawnbetween lawinvariant risk measures and divergences,which we define as functionals of pairs of probability measures on arbitrary standard Borel spaces satisfying a few natural properties.
