Show moreThis thesis consists of three chapters, the first two of which concern division points of elements of the multiplicative group of a number field. The third chapter involves division points of points on an elliptic curve with complex multiplication over a number field. Show less
We bound Arakelov invariants of curves in terms of their Belyi degree. We give three applications which are algorithmic, geometric and Diophantine of nature, respectively
