Higgs bundles and fundamental group schemes [PDF]

Advances in Geometry, 2016
Relying on a notion of “numerical effectiveness” for Higgs bundles, we show that the category of “numerically flat” Higgs vector bundles on a smooth projective variety X is a Tannakian category. We introduce the associated group scheme, that we call the “

Saturation rank for finite group schemes: Finite groups and infinitesimal group schemes [PDF]

Forum Mathematicum, 2017
Abstract We investigate the saturation rank of a finite group scheme defined over an algebraically closed field 𝕜 {\Bbbk} of positive characteristic ...

Torsion group schemes as iterative differential Galois groups [PDF]

, 2015
We are considering iterative derivations on the function field L of abelian schemes in positive characteristic p>0, and give conditions when the torsion group schemes of this abelian scheme occur as ID-automorphism groups, i.e.

Hironaka’s additive group schemes [PDF]

Nagoya Mathematical Journal, 1973
In [1] and [2], Hironaka referred to the importance of an additive group scheme BPn,P, which is associated with a point p in Pn, in connection with the resolution of singularities in characteristic p > 0. Also he showed that if the dimension of BPn,p is not greater than p, then it is a vector group.

Bivariate representation and conjugacy class zeta functions associated to unipotent group schemes, II: Groups of type F, G, and H

International journal of algebra and computation, 2018

Polylogarithm for families of commutative group schemes [PDF]

, 2015
We generalize the definition of the polylogarithm classes to the case of commutative group schemes, both in the sheaf theoretic and the motivic setting. This generalizes and simplifies the existing cases.

INVARIANTS OF FINITE GROUP SCHEMES [PDF]

Journal of the London Mathematical Society, 2002
We investigate the algebras of invariants and the properties of the quotient morphism by an action of a finite group scheme in terms of stabilizers of points.

Professional farmer collectives for effective agri-environmental management: an assessment

International Journal of Agricultural Sustainability, 2023
In 2013 the EU Common Agricultural Policy (CAP) enabled groups of farmers to be applicants and final beneficiaries of Agri-environmental schemes (AES).

Results-based agri-environmental schemes can reflect habitat integrity for a non-target taxonomic group: Carabidae

Ecological Indicators, 2023
Results-based agri-environment schemes are emerging as a valuable tool to incentivise optimal management of farmed habitats for biodiversity targets. Results-based payment schemes in Ireland use multicriteria assessments to score habitat integrity for ...

Two-particle irreducible functional renormalization group schemes—a comparative study [PDF]

, 2015
We derive functional renormalization group (fRG) schemes for Fermi systems which are based on the two-particle irreducible approach to the quantum many-body problem.
