Counting curves and their rational points
n this thesis we study curves. In the first half, we study moduli spaces of curves and Gromov-Witten invariants, certain kinds of curves counts. We employ logarithmic geometry for this.

Some major results include the polynomiality of the double ramification cycle and recursive relations for the log double ramification cycle. In the second half we study rational points on curves, in particular Chabauty's method for finding the rational points and extensions of it. Major results include that the geometric (quadratic) Chabauty method is theoretically stronger than the original (quadratic) Chabauty method, and that local heights for quadratic Chabauty are explicitly computable.
