This question is often cast as a dichotomy between competing theoretical perspectives. Theorists like Ekman argue for the primacy of emotion as a determinant of nonverbal behavior: emotions “leak” and only indirectly serve socia...

‘Nature does not take leaps,’ the scientist says, ‘There are always overlaps, bridges or something else in between.’ But why should Psyche – the most beautiful daughter of Physis (Nature) – take leaps, even when she is ill? ‘Because Emil Kraepelin decided so 110 years ago’, say some psychiatrists, and they add ‘The Kraepelinian dichotomy is – as we hope – well known to all of you’.

By using orthogonal changes of variables, the original DAE system is transformed into appropriate condensed forms, for which concepts such as Lyapunov exponents, Bohl exponents, exponential dichotomy and spectral intervals of variou...
