In this paper, we present a method for constructing a Jacobi matrix [Formula: see text] using [Formula: see text] known eigenvalues [Formula: see text]. Some conditions are also given under which the constructed matrix is nonnegative and its diagonal

Stochastic integro-differential equations are obtained when we consider prices jump in financial modelling. In this paper, these equations are solved numerically by applying the two-dimensional Tau method with ordinary bases. Next, the numerical solu

Using mathematical models to simulate biological systems has a long history. An increasing number of such models have been applied to various aspects of tumor growth, with the ultimate goal of controlling cancer. Nevertheless, very little has been do

In this paper we consider the variants of Gram–Schmidt such as Classical Gram–Schmidt and Modified Gram–Schmidt algorithms. It is shown that for problems of dimension more than two the round-off error of operation \({q_1}^Tq_2\) has more propag

In this paper, we introduce and define a new metric on the space of fuzzy continuous functions in the fractional calculus. Regarding this metric and using the well-known Banach fixed point theorem, we provide some conditions that guarantee the existe

Using parametric form of fuzzy functions, we convert a linear two-dimensional fuzzy Fredholm integral equation of the second kind (2D-FFIE-2) to a linear system of Fredholm integral equations of the second kind with three variables in crisp case. In
