Discrete Hashimoto surfaces and a doubly discrete smokering flow
Tim Hoffmann
Bäcklund transformations for smooth and ``space discrete'' Hashimoto surfaces are discussed and a geometric interpretation is given. It is shown that the complex curvature of a dis…

Conformally symmetric circle packings. A generalization of Doyle spirals
Alexander I. Bobenko, Tim Hoffmann
From the geometric study of the elementary cell of hexagonal circle packings --- a flower of 7 circles --- the class of conformally symmetric circle packings is defined. Up to Moeb…
