On base sizes for actions of finite classical groups [PDF]

, 2007
Let G be a finite almost simple classical group and let ? be a faithful primitive non-standard G-set. A base for G is a subset B C_ ? whose pointwise stabilizer is trivial; we write b(G) for the minimal size of a base for G.

Generalised quadrangles with a group of automorphisms acting primitively on points and lines [PDF]

, 2011
We show that if G is a group of automorphisms of a thick finite generalised quadrangle Q acting primitively on both the points and lines of Q, then G is almost simple.

Wave-Shaped Round Functions and Primitive Groups [PDF]

, 2018
Round functions used as building blocks for iterated block ciphers, both in the case of Substitution-Permutation Networks and Feistel Networks, are often obtained as the composition of different layers which provide confusion and diffusion, and key ...

Rough ends of infinite primitive permutation groups [PDF]

, 2012
If G is a group of permutations of a set Omega , then the suborbits of G are the orbits of point-stabilisers G_\alpha acting on Omega. The cardinalities of these suborbits are the subdegrees of G. Every infinite primitive permutation group G with finite

On derangements in simple permutation groups

Forum of Mathematics, Sigma
Let $G \leqslant \mathrm {Sym}(\Omega )$ be a finite transitive permutation group and recall that an element in G is a derangement if it has no fixed points on $\Omega $ . Let $\Delta (G)$ be the set of derangements in G and define

A single source theorem for primitive points on curves

Forum of Mathematics, Sigma
Let C be a curve defined over a number field K and write g for the genus of C and J for the Jacobian of C. Let $n \ge 2$ . We say that an algebraic point $P \in C(\overline {K})$ has degree n if the extension $K(P)/K$ has degree n. By

Transitive simple subgroups of wreath products in product action

, 2003
A transitive simple subgroup of a finite symmetric group is very rarely contained in a full wreath product in product action. All such simple permutation groups are determined in this paper.

Distinguishability of infinite groups and graphs [PDF]

, 2011
The distinguishing number of a group G acting faithfully on a set V is the least number of colors needed to color the elements of V so that no non-identity element of the group preserves the coloring.

Transcriptional regulation in cowpea bruchid guts during adaptation to a plant defense protease inhibitor and screening of mutants that are altered in jasmonate-regulated signal transduction pathways using Arabidopsis thaliana [PDF]

, 2009
To study the interaction between plants and insects I performed the experiments to find out the counter-defense mechanism of insects when insects were attacked by the defense protein of plants.
