An Application of Fuzzy Multiple Linear Regression in Biological Paradigm
Complexity, 2022 The regression model is generally utilized in several fields of study because of its applications. Regression is an extremely incredible approach; it builds up a connection between dependent and independent variables.

Exterior products of operators and superoptimal analytic approximation
Transactions of the London Mathematical Society, Volume 8, Issue 1, Page 299-412, December 2021., 2021 Abstract We give a new algorithm for the construction of the unique superoptimal analytic approximant of a given continuous matrix‐valued function on the unit circle, using exterior powers of operators in preference to spectral or Wiener–Masani factorizations.

Compact weighted composition operators and fixed points in convex domains [PDF]
, 2006 We extend a classical result of Caughran/Schwartz and another recent result of Gunatillake by showing that if D is a bounded, convex domain in n-dimensional complex space, m is a holomorphic function on D and bounded away from zero toward the boundary of

Weighted holomorphic Besov spaces on the polydisk
Journal of Function Spaces, Volume 9, Issue 1, Page 1-16, 2011., 2011 This work is an introduction of weighted Besov spaces of holomorphic functions on the polydisk. Let Un be the unit polydisk in Cn and S be the space of functions of regular variation. Let 1 ≤ p < ∞, ω = (ω1, …, ωn), ωj ∈ S(1 ≤ j ≤ n) and f ∈ H(Un). The function f is said to be an element of the holomorphic Besov space Bp(ω) if ‖f‖Bp(ω)p=∫Un |Df(z)|p∏j ...

Journal of Function Spaces, Volume 9, Issue 3, Page 217-244, 2011., 2011 I. Vekua’s integral representations of holomorphic functions, whose m‐th derivative (m ≥ 0) is Hӧlder‐continuous in a closed domain bounded by the Lyapunov curve, are generalized for analytic functions whose m‐th derivative is representable by a Cauchy type integral whose density is from variable exponent Lebesgue space Lp(⋅)(Γ; ω) with power weight ...

A hyperbolic universal operator commuting with a compact operator [PDF]
, 2019 A Hilbert space operator is called universal (in the sense of Rota) if every operator on the Hilbert space is similar to a multiple of the restriction of the universal operator to one of its invariant subspaces.

Generalized composition operators from Bloch type spaces to QK type spaces
Journal of Function Spaces, Volume 8, Issue 1, Page 55-66, 2010., 2010 This paper characterizes the boundedness and compactness of the generalized composition operator (Cφgf)(z)=∫0zf′(φ(ξ))g(ξ)dξ from Bloch type spaces to QK type spaces.

Journal of Function Spaces, Volume 7, Issue 3, Page 301-311, 2009., 2009 Recently V. Kokilashvili, N. Samko, and S. Samko have proved a sufficient condition for the boundedness of the Cauchy singular integral operator on variable Lebesgue spaces with radial oscillating weights over Carleson curves. This condition is formulated in terms of Matuszewska‐Orlicz indices of weights. We prove a partial converse of their result.

Disjoint hypercyclicity equals disjoint supercyclicity for families of Taylor-type operators
Open Mathematics, 2018 We characterize disjointness of supercyclic operators which map a holomorphic function to a partial sum of the Taylor expansion. In particular, we show that disjoint hypercyclicity equals disjoint supercyclicity for families of Taylor-type operators ...

Extended Cesáro operators between generalized Besov spaces and Bloch type spaces in the unit ball
Journal of Function Spaces, Volume 7, Issue 3, Page 209-223, 2009., 2009 Let 𝑔 be a holomorphic of the unit ball B in the n‐dimensional complex space, and denote by Tg the extended Cesáro operator with symbol g. Let 0 < p < +∞, −n − 1 < q < +∞, q > −1 and α > 0, starting with a brief introduction to well known results about Cesáro operator, we investigate the boundedness and compactness of Tg between generalized Besov space
