Abstract This paper establishes the Manin conjecture for a certain non-split singular del Pezzo surface of degree four $X \subset \bfP^4$. In fact, if U ⊂ X is the open subset formed by deleting the lines from X, and H is the usual projective height function on $\bfP^4(\Q)$, then the height zeta function $ \sum_{x \in U(\Q)}{H(x)^{-s}} $ is analytically continued to the half-plane ℜe(s) > 17/20.

For split smooth Del Pezzo surfaces, we analyse the structure of the effective cone and prove a recursive formula for the value of $\alpha$, appearing in the leading constant as predicted by Peyre of

Counting Points On Varieties Using Universal Torsors

Around 1989, Manin initiated a program to understand the asymptotic behaviour of rational points of bounded height on Fano varieties. This program led to the search of new methods to estimate the
