Fixed point theory is a central topic in functional analysis that examines conditions under which a mapping in a Banach space admits points that remain invariant under the transformation.

Matrix splitting iteration methods have emerged as potent tools in addressing complementarity problems, which frequently arise in optimisation, economics and engineering applications.

The scattergraph method is a visual accounting technique used to separate fixed and variable components of semi-variable expenses by plotting data points on a graph. What Is the Scattergraph Method?
