Anderson notes that the interview took place at an important point in Wolff’s life: the premiere of his piece Burdocks (1971)—the climax of his association with the English composer Cornelius Cardew—and his first year teaching music at Dartmout

Geometric invariance of determining and resonating centers: Odd- and any-number limitations of Pyragas control

Autor: de Wolff, B., Schneider, I.

In the spirit of the well-known odd-number limitation, we study failure of Pyragas control of periodic orbits and equilibria. Addressing the periodic orbits first, we derive a fundamental observation on the invariance of the geometric multiplicity of
