Lines on -adic and real cubic surfaces
Rida Ait El Manssour, Yassine El Maazouz, Enis Kaya +1
We study lines on smooth cubic surfaces over the field of -adic numbers, from a theoretical and computational point of view. Segre showed that the possible counts of such lines…

Multiplicity structure of the arc space of a fat point
Rida Ait El Manssour, Gleb Pogudin
The equation defines a fat point on a line. The algebra of regular functions on the arc space of this scheme is the quotient of by all differe…

Probabilistic enumerative geometry over -adic numbers: linear spaces on complete intersections
Rida Ait El Manssour, Antonio Lerario
We compute the expectation of the number of linear spaces on a random complete intersection in -adic projective space. Here "random" means that the coefficients of the polynomia…
