Resonance contributions $$\phi (1020, 1680)\rightarrow K\bar{K}$$ ϕ ( 1020 , 1680 ) → K K ¯ for the three-body decays $$B\rightarrow K\bar{K} h$$ B → K K ¯ h

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study the contributions for the $$K^+K^-$$ K + K - and $$K^0\bar{K}^0$$ K 0 K ¯ 0 originating from the intermediate states $$\phi (1020)$$ ϕ ( 1020 ) and $$\phi (1680)$$ ϕ ( 1680 ) in the charmless three-body decays $$B\rightarrow K\bar{K} h$$ B → K K

Quasi-two-body decays $$B_{(s)}\rightarrow K^*(892)h\rightarrow K\pi h$$ B(s)→K∗(892)h→Kπh in perturbative QCD approach [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We extend our recent works on the P-wave two-pion resonant contributions to the kaon-pion cases in the hadronic charmless B meson decays by employing the perturbative QCD approach. The concerned decay modes are analysed in the quasi-two-body framework by

Integral K-operator frames for B(H)

open access: yesAnnals of the University of Craiova - Mathematics and Computer Science Series, 2021
In this paper, we will introduce a new notion, that of $K$-Integral operator frames in the set of all bounded linear operators noted $\mathcal{B}(H)$, where $H$ is a separable Hilbert space. Also, we prove some results of integral $K$-operator frame.

Sample Path Properties of Bifractional Brownian Motion [PDF]

open access: yes, 2007
Let $B^{H, K}= \big\{B^{H, K}(t), t \in \R_+ \big\}$ be a bifractional Brownian motion in $\R^d$. We prove that $B^{H, K}$ is strongly locally nondeterministic.

Limits of bifractional Brownian noises [PDF]

open access: yes, 2008
Let $B^{H,K}=(B^{H,K}_{t}, t\geq 0)$ be a bifractional Brownian motion with two parameters $H\in (0,1)$ and $K\in(0,1]$. The main result of this paper is that the increment process generated by the bifractional Brownian motion $(B^{H,K}_{h+t} -B^{H,K}_{h}
