    800 conics on a smooth quartic surface
    (Elsevier BV * North-Holland, 2022-03-10) Degtyarev, Alex
    We construct an example of a smooth spatial quartic surface that contains 800 irreducible conics. © 2022 Elsevier B.V.

    Conics on Kummer quartics
    (Tohoku Daigaku Suugaku Kyoshitsu,Tohoku University, Mathematical Institute, 2023-09-25) Degtyarev, Alex
    We classify the configurations of lines and conics in smooth Kummer quartics, assuming that all 16 Kummer divisors map to conics. We show that the number of conics on such a quartic is at most 800.
