A general Approach to Methods with a Sparse Jacobian for Solving Nonlinear Systems of Equations

Kyurkchiev, Nikolay, Iliev, Anton (2007)

2000 Mathematics Subject Classification: 65H10. Here we give methodological survey of contemporary methods for solving nonlinear systems of equations in Rn. The reason of this review is that many authors in present days rediscovered such classical methods. In particular, we consider Newton’s-type algorithms with sparse Jacobian. Method for which the inverse matrix of the Jacobian is replaced by the inverse matrix of the Vandermondian is proposed. A number of illustrative numerical...

Proximinality and co-proximinality in metric linear spaces

T.D. Narang, Sahil Gupta (2015)

As a counterpart to best approximation, the concept of best coapproximation was introduced in normed linear spaces by C. Franchetti and M. Furi in 1972. Subsequently, this study was taken up by many researchers. In this paper, we discuss some results on the existence and uniqueness of best approximation and best coapproximation when the underlying spaces are metric linear spaces
