Gauss-Manin stratification and stratified fundamental group schemes [PDF]

open access: yes, 2012
We defined the Gau\ss-Manin stratification of a stratified bundle with respect to a smooth morphism and use it to study the homotopy sequence of stratified fundamental group schemes.Comment: 14 pages, the proof of Prop. 2.8 is corrected.

Hironaka’s additive group schemes [PDF]

open access: yesNagoya 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.

INVARIANTS OF FINITE GROUP SCHEMES [PDF]

open access: yesJournal 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

open access: yesInternational 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).

Graded group schemes and graded group varieties [PDF]

open access: yesCommunications in Algebra, 2016
We define graded group schemes and graded group varieties and develop their theory. Graded group schemes are the graded analogue of group schemes and are in correspondence with graded Hopf algebra. In this setting, graded group varieties take the place of infinitesimal group schemes; an important and well studied class of group schemes.

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

open access: yesEcological 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 ...

The pseudo-fundamental group scheme [PDF]

open access: yesJournal of Algebra, 2019
Let $X$ be any scheme defined over a Dedekind scheme $S$ with a given section $x\in X(S)$. We prove the existence of a pro-finite $S$-group scheme $\aleph(X,x)$ and a universal $\aleph(X,x)$-torsor dominating all the pro-finite pointed torsors over $X$.

Almost Fully Secured Lattice-Based Group Signatures with Verifier-Local Revocation

open access: yesCryptography, 2020
An efficient member revocation mechanism is a desirable feature when group signature schemes are applied in practical scenarios. Revocation methods, such as verifier-local revocation (VLR), provide an efficient member revocation in applications of group ...
