  Quaternion group - Wikipedia, the free encyclopedia
The inner automorphism group of Q is isomorphic to Q modulo its center, and is therefore also isomorphic to the Klein four-group.
The quaternion group Q may be regarded as acting on the eight nonzero elements of the 2-dimensional vector space over the finite field GF(3).
The generalized quaternion groups are members of the still larger family of dicyclic groups.

In classical mechanics, the Hamiltonian is a function describing the state of a mechanical system in terms of position and momentum variables.
Both the Hamiltonian operator in physics and Hamiltonian cycles in graph theory are named after Sir William Rowan Hamilton.

 Hamiltonian group - Wikipedia, the free encyclopedia
In group theory, a non-abelian group G is called Hamiltonian if every subgroup of G is normal.
Clearly, every abelian group has this property, because all subgroups of an abelian group are normal subgroups, but there are non-abelian examples as well.

In group theory, the quaternion group is a non-abelian group of order 8 with a number of interesting properties.
Note that the resulting group is non-commutative; for example ij = -ji.

Nilpotent groups arise in (Group theory applied to the solution of algebraic equations) Galois theory, as well as in the classification of groups.
Every abelian group is nilpotent of class 1, except for the trivial group, which is nilpotent of class 0.
Every subgroup of a nilpotent group of class n is nilpotent of class at most n; in addition, if f is a (Similarity of form) homomorphism of a nilpotent group of class n, then the image of f is nilpotent of class at most n.

In the mathematical field of graph theory, a Hamiltonian path is a path in a undirected graph which visits each vertex exactly once.
Hamiltonian paths and cycles are named after William Rowan Hamilton who invented the icosian game, now also known as ''Hamilton's puzzle, which involves finding a Hamiltonian cycle in the edge graph of the dodecahedron.
A Hamiltonian cycle, Hamiltonian circuit, vertex tour or graph cycle is a cycle that visits each vertex exactly once (excluding the start/end vertex).

In the case where the moment map for the action is proper, we prove an infinite-dimensional analog of Kirwan's surjectivity theorem, which shows that the equivariant cohomology ring of the manifold gives a set of generators for the cohomology ring of the reduced space.
In the case of the smallest coadjoint orbit of the loop group, our function coincides with the energy function whose perfection plays a key role in the classical proof of Bott periodicity.
In the case of Hamiltonian LG-spaces arising from Yang-Mills theory, the function we study is closely related to the Yang-Mills functional whose Morse-theoretic properties were first studied by Atiyah and Bott.

We show that\, in an appropriat e sense\, the square of the moment map is an equivariantly perfect Morse f unction on such a space.
Examples of such spaces are coadjoint orbits of the lo op group (where the Morse function is the classical energy functional of Morse and Bott) and spaces arising from Yang-Mills theory in two dimension s.

One of the key theoretical aims of this project is to extend these techniques to singular points of momentum maps and to investigate phenomena associated to discrete (possibly time-reversing) symmetries and non-compact symmetry groups.
One of the aims of the network is to adapt and combine these with standard non-symmetric Hamiltonian methods to initiate a theory of Hamiltonian symmetric chaos.
For REs these are provided by existing local descriptions of Hamiltonian group actions while for RPOs these will be combined with bundle techniques already developed in the analogous non-Hamiltonian context.

 Biophysics & Statistical Physics Group: non-Hamiltonian molecular dynamics
Although (Hamiltonian) molecular dynamics has proven to be a very useful tool, it has one basic restriction: It can in principle generate only equilibrium properties of the microcanonical ensemble.
Although the mechanical consequences of this procedure might be straightforward, the implications on the statistical mechanics of the system are less evident.
In general the extended Lagrangians cannot be transformed into Hamiltonian form; hence the name non-Hamiltonian molecular dynamics.

Hamiltonian torus actions are classified by Delzant in the ``completely integrable case''.
The ``almost but not quite completely integrable'' case is classified in joint work with Sue Tolman.
