Abstract
AbstractWe compute the cones of effective divisors on blowups of $$\mathbb P^1 \times \mathbb P^2$$
P

and $$\mathbb P^1 \times \mathbb P^3$$

P

in up to 6 points. We also show that all these varieties are log Fano, giving a conceptual explanation for the fact that all the cones we compute are rational polyhedral.
