Negative parity nonstrange baryons in large $N_c$ QCD: quark excitation versus meson-nucleon scattering

, 2011
We show that the two complementary pictures of large $N_c$ baryons - the single-quark orbital excitation about a symmetric core and the meson-nucleon resonance -- are compatible for $\ell$ = 3 SU(4) baryons.

APPROXIMATION BY STANCU TYPE JAKIMOVSKI-LEVIATAN-PALTANEA OPERATORS

TWMS Journal of Applied and Engineering Mathematics, 2019
The present article deals with the general family of summation-integral type operators. Here, we introduce the Stancu type generalization of the Jakimovski-LeviatanPăltănea operators and study Voronovskaja-type asymptotic theorem, local approximation, weighted approximation, rate of convergence and pointwise estimates using the Lipschitz type maximal ...

Shape-preserving and convergence properties of q-Stancu operator(q-Stancu算子的保形性及收敛定理)

Zhejiang Daxue xuebao. Lixue ban, 2009
给出了基于q-整数的Stancu算子Ln(•,q）,同时研究了该算子的一些基本性质.首先,利用q-Stancu算子作用于某一函数f(x)以后Ln(f,q;x)与f(x)变号数的关系,得到了该算子的保形性定理.其次,通过精细的不等式放缩,该算子作用于一般的连续函数后收敛于一极限算子,而不像一般算子那样收敛于函数本身,并用光滑模刻画了其收敛速度.

On a q-analogue of Stancu operators

Open Mathematics, 2010
Abstract This paper is concerned with a generalization in q-Calculus of Stancu operators. Involving modulus of continuity and Lipschitz type maximal function, we give estimates for the rate of convergence. A probabilistic approach is presented and approximation properties are established.

Chlodowsky variant of Bernstein-type operators on the domain

Open Mathematics
In the present paper, we deal with Bernstein-Chlodowsky type operators for approximating functions on the domain. We first present Bernstein-Chlodowsky type operators in two variables and then we discuss some examples of these operators under a domain ...

Convergence by Class of Kantorovich-Type q-Szász Operators and Comprehensive Results

Mathematics
In this paper, we primarily use Stancu variants of Kantorovich-type operators to investigate the convergence and other associated properties of new Szász–Mirakjan operators.
