商品簡介
Degtyarev (Bilkent U., Ankara, Turkey) explores ramifications of the close relation between elliptic surfaces and trigonal curves in ruled surfaces, skeletons (also called dessins d'enfants and quilts among other things), and subgroups of the modular group gamma : = PSL(2,Z). At a level suitable to advanced students and researchers in mathematics and theoretical physics, he summarizes, unifies, and extends a number of results in articles that he published or submitted during the past five years in collaboration with several colleagues. The work remains in progress, he warns, so he presents some of the older results in a more complete and general form as well as introducing new results.
