Completely Reachable Automata, Primitive Groups and the State Complexity of the Set of Synchronizing Words

Language and Automata Theory and Applications, 2020
We give a new characterization of primitive permutation groups tied to the notion of completely reachable automata. Also, we introduce sync-maximal permutation groups tied to the state complexity of the set of synchronizing words of certain associated ...

Finding Objects by Grouping Primitives

Conference Record of Thirty-Second Asilomar Conference on Signals, Systems and Computers (Cat. No.98CH36284), 1999
We describe the use of a representation, called a body plan, to segment and to recognize people and animals in complex environments. The representation is an organized collection of grouping hints obtained from a combination of constraints on color and texture and constraints on geometric properties such as the structure of individual parts and the ...

Primitive Group Treatment

Psychopathology, 1978
Although it has been known for many years that hallucinogenic drugs are used by witch doctors in the Peruvian jungles for therapeutic purposes, there have been no descriptions of their use. We studied one type of treatment carried out in groups of about 10 to 12 ‘patients’, where the healer makes a magical diagnosis and provides a potion, usually ...

Finite primitive groups and edge-transitive hypergraphs

, 2014
We determine all finite primitive groups that are automorphism groups of edge-transitive hypergraphs. This gives an answer to a problem proposed by Babai and Cameron.

On Primitive Solvable Linear Groups

Canadian Journal of Mathematics, 1971
Let V be a vector space over the field K. A group G of K-linear transformations of V onto itself is primitive in case no proper nontrivial subspace of V is G-invariant and V cannot be written as a direct sum of proper subspaces permuted among themselves by G.

Group Interrogation: A Group Programming Primitive

1997
Group communication is becoming an increasingly important communication paradigm of modern distributed systems, but programming-level support for group communication is hitherto missing. Remote procedure call is a familiar programming-level abstraction to support unicast “request-response-style” communication.

Action of primitive groups

Algebra and Logic, 1989
In the paper graphs of finite valency d are considered which admit a vertex primitive group of automorphisms. Theorem 1. Let \(d,r\in {\mathbb{N}}\) and \(f:{\mathbb{N}}\cup \{0\}\to {\mathbb{N}}\cup \{0\}\) such that \(f(n)=o(n)\) as \(n\to \infty.\) There exists a natural number c(d,f,r)\(\geq 1\) such that if G is a primitive group of automorphisms ...
