Linear approximation is a method used to estimate the value of a function near a given point using the tangent line at that point. This technique simplifies complex functions into a linear form ...

Solution to strongly nonlinear parabolic problems by a linear approximation scheme Abstract: A nonlinear parabolic problem is solved by a linear approximation scheme using a nonstandard time ...

Abstract: A certain approximation scheme based on "piecewise linear" approximations of L 2 spaces is employed to formulate a numerical method for solving quadratic optimal control problems governed by ...
