Ander Murua coauthored complex-coefficient <operator splitting> methods with <Sergio Blanes> and <Fernando Casas>. They analyze how composition coefficients influence order and error propagation. Positive real parts allow complex-time substeps to bypass an obstruction associated with negative real coefficients, particularly relevant to dissipative evolution equations.<Splitting methods with complex coefficients by Sergio Blanes and others>[Abstract and Section 1]{ref}
