The arithmetic of trees

Adriano Bruno, Dan Yasaki

The arithmetic of the natural numbers can be extended to arithmetic operations on planar binary trees. This gives rise to a non-commutative arithmetic theory. In this exposition, w…

Prediction and measurement of transient responses of first difference based chaos control for 1-dimensional maps

Edward H. Hellen, J. Keith Thomas

Chaotic behavior can be produced from difference equations with unstable fixed points. Difference equations can be used for algorithms to control the chaotic behavior by perturbing…

Spectropolarimetry of the Massive Post-Red Supergiants IRC +10420 and HD 179821

M. Patel, R. D. Oudmaijer, J. S. Vink +5

We present medium resolution spectropolarimetry and long term photo-polarimetry of two massive post-red supergiants, IRC +10420 and HD 179821. The data provide new information on t…
