Family of elliptic curves in $\mathbb P^3$
For points $p_1=[1,0,0,0], p_2=[0,1,0,0], p_3=[0,0,1,0]$, $p_4=[0,0,0,1]$ and $p_5=[1,1,1,1]$
in the projective space $\mathbb P^3$, Let $l_{ij}$ be the line through $p_i, p_j$.
Let
$$C=l_{12} \cup …

Deformation of a singular CY manifold
Let me explain more concretely what's happening.
Choose a smooth quintic hypersurface $W$ in $\mathbb C \mathbb P^4$ that intersect transversely with $X \cap Y$. Then $W$ and $X+Y$ are linearly equiv …
