Outline of Final Research Achievements

Our main results are on the global structure of spiral tilings with similarity symmetry, and on the transversality of holomorphic foliations with spheres, having the symmetry of complex conjugacy. The parameter space of quadrilateral Voronoi spiral tilings is written as a family of real algebraic curves, which is related to the continued fraction expansion of the divergence angle. The limit set of the shapes of tiles also relates to the continued fraction expansion. As an application of phyllotactic geometry, we propose phyllotactic configurations of seats in a colosseum.
The transversality of holomorphic foliations with spheres is studied from the viewpoint of a complex-conjugate dynamical system. In a good condition, the variety of contact is a real two-dimensional manifold.
