Bivariate matrix functions [PDF]
Operators and Matrices, 2014 A definition of bivariate matrix functions is introduced and some theoretical as well as algorithmic aspects are analyzed. It is shown that our framework naturally extends the usual notion of (univariate) matrix functions and allows to unify existing results on linear matrix equations and derivatives of matrix functions.

Generalized wavelet decompositions of bivariate functions [PDF]
Proceedings of the American Mathematical Society, 1994 The objective of this paper is to introduce an integral transform of wavelet-type on L 2 ( R 2 ) {L^2}({R^2}) that can be applied to decompose the space L 2

Bivariate Flood Frequency Analysis Using the Copula Archimedean Function (Gumbel–Hougaard) [PDF]
پژوهشهای آبخیزداری, 2020 Flood is a multivariate and complex phenomenon that has a random nature. In conventional methods of flood frequency analysis, only flood peak variable is important and it is assumed that the variable under consideration follows a particular parametric ...

New Results On the Sum of Two Generalized Gaussian Random Variables [PDF]
, 2015 We propose in this paper a new method to compute the characteristic function (CF) of generalized Gaussian (GG) random variable in terms of the Fox H function. The CF of the sum of two independent GG random variables is then deduced. Based on this results,

Entire bivariate functions of exponential type [PDF]
Bulletin of Mathematical Sciences, 2015 Summary: In this paper, we will analysis the concepts of bivariate entire complex valued functions of exponential type. To accomplish this goal, we begin with the presentation of a notion of bounded index for bivariate complex functions. Using this notion we present a series of sufficient conditions that ensure that exponential type is preserved.

Mathematical and Computational Applications, 2022 The generalized half-logistic distribution is ideal to fit the lifetime of some products, such as ball bearings and electrical insulation. In this paper, we aim to extend this scope by creating a motivated bivariate version.

Viscovatov-Like Algorithm of Thiele–Newton’s Blending Expansion for a Bivariate Function
Mathematics, 2019 In this paper, Thiele−Newton’s blending expansion of a bivariate function is firstly suggested by means of combining Thiele’s continued fraction in one variable with Taylor’s polynomial expansion in another variable.

A bivariate Chebyshev polynomials method for nonlinear dynamic systems with interval uncertainties
Nonlinear dynamics, 2021 A bivariate Chebyshev polynomials approach is proposed to estimate the dynamic response bounds of nonlinear systems with interval uncertainties. The existing collocation method directly searches the maximum and minimum values of the surrogate model in ...

On the representation by bivariate ridge functions [PDF]
Ukrains’kyi Matematychnyi Zhurnal, 2021 UDC 517.5 We consider the problem of representation of a bivariate function by sums of ridge functions. It is shown that if a function of a certain smoothness class is represented by a sum of finitely many arbitrarily behaved ridge functions, then it can also be represented by a sum of ridge functions of the same smoothness class.
