On the one hand this allows us to bound the dimension of the singular locus of the moduli space of rational curves on such hypersurfaces and, on the other hand, it sheds light on Peyre’s reformulation of the Batyrev–Manin conjecture in terms of slopes with respect to the tangent bundle."}],"department":[{"_id":"TiBr"}],"volume":17,"intvolume":"        17","year":"2023","acknowledgement":"The authors are grateful to Paul Nelson, Per Salberger and Jason Starr for useful comments.
