We review the way to analytically continue the Lippmann–Schwinger bras and kets into the complex plane. We will see that a naive analytic continuation leads to non-sensical results in resonance theory, and we will explain how the non-obvious but correct analytical continuation is done. We will see that the physical basis for the non-obvious but correct(More)
In this work we present an application developed in Derive 6 to compose counterpoints for a given melody (" cantus firmus "). The result is non deterministic, so different counterpoints can be generated for a fixed melody, all of them obeying classical rules of counterpoint. It is also possible that the counterpoint could not be generated, in this case,(More)
