One step integration methods of third-fourth order accuracy with large hyperbolic stability limits
A class of stability polynomials of K-stage methods is given for which the interval of stability on the imaginary axis is \(\sqrt{(K-1)^ 2-1}\). For K odd, \(K\geq 3\), the order of accuracy is 3 while for K even, \(K\geq 4\), it is 4.
