Finding the extrema of a multivariable function is an essential skill in calculus and applied mathematics. This process allows you to determine the minima and maxima of a function across multiple ...

Abstract: A method of generating a multivariable positive real function (MPRF) from the given multivariable real part is presented. The constraints on the given real part, in addition to its ...

Abstract: Traditional developments of the multivariable circle criterion have assumed continuity of the nonlinearity. This paper shows that the stability results of the multivariable circle criterion ...
