Obstructions to deforming space curves lying on a smooth cubic surface

Hirokazu Nasu

In this paper, we study the deformations of curves in the projective 3-space $P^{3}$ (space curves), one of the most classically studied objects in algebraic geometry. We pro…

Obstructions to deforming curves on an Enriques-Fano 3-fold

Hirokazu Nasu

We study the deformations of a curve $C$ on an Enriques-Fano $3$ -fold $X \subset P^{n}$ , assuming that $C$ is contained in a smooth hyperplane section $S \subset X$ , that is…
