On the arithmetic and geometry of spaces

Michel Matignon, Guillaume Pagot, Daniele Turchetti

Let be a prime number. Motivated by the local lifting problem for with , we prove several new results on certain -vector spaces…

On M-O.Ore determinants

Jean Fresnel, Michel Matignon

The existence of certain Fq-spaces of differential forms of the projective line over a field K containing Fq leads us to prove an identity linking the determinant of the Moore matr…

Good rings and homogeneous polynomials

J. Fresnel, Michel Matignon

In 2011, Khurana, Lam and Wang define the following property. (*)A commutative unital ring A satisfies the property ''power stable range one'' if for all a, b A with aA + bA…

Big Actions with non abelian derived subgroup

Pierre Chrétien, Michel Matignon

For any we give an example of big action with non abelian derived subgroup. It is obtained as a covering of a curve related to the Ree curve.

Maximal monodromy in unequal characteristic

Pierre Chrétien, Michel Matignon

Let be a complete discrete valuation ring of mixed characteristic with fraction field . We study stable models of -cyclic covers of $\Proj_K$. First, we determine…

On smooth curves endowed with a large automorphism -group in characteristic

Michel Matignon, Magali Rocher

Let be an algebraically closed field of characteristic and a connected nonsingular projective curve over with genus . This paper continues the work begu…
