This course covers the geometry of Riemann surfaces, in particular the theories on intersection points of regular mapping between compact Riemann surfaces, including the newest material. As the lecture progresses, the instructor will deal with differential forms, Hodge decomposition, Jacobian varieties, and the Lefschetz trace formula. This course is a continuation of Advanced Geometry 4 (Special Lectures on Geometry IV) offered in 2014, but fundamentals will be covered again, so students will be able to follow the lectures even if they take this course alone.
Students will gain an understanding of the newest topics in this field. To solidify understanding, exercise problems will be given out during lecture, for students to submit as a report.
To determine the existence and estimate the number of solutions of a given equation is one of the fundamental problems in mathematics. To estimate the number of coincidences of morphisms between manifolds is a version of manifolds of this problem.
This course deals with Riemann surfaces which are of minimal dimension as complex manifolds. Several simple theorems are given by virtue of the low dimension.
By completing this course, students will be able to understand the latest topics in this field.
Riemann surfaces, differential forms, Hodge decomposition, Jacobian varieties, the Lefschetz trace formula.
