The possible feedback invariants of a linear time-invariant dynamical system, represented by a pair of matrices (A, B), are studied when the only information about the system is that it has an (A, B)-invariant subspace, S, whose restriction is an autonomous system and the quotient is controllable.

β¦ Synopsis
We introduce two "polynomial invariants" for rooted trees and discuss their properties.
A statistical mechanics interpretation is pointed out. In particular, we show that the partition function of the Ising model, in the simple surface separation ensemble, is a complete invariant.

Negami has introduced two polynomials for graphs and proved a number of properties of them. In this note, it is shown that these polynomials are intimately related to the well-known Tutte polynomial. This fact is used, together with a result of Brylawski, to answer a question of Negami. The matroid
We present a review of a theoretical study at the microscopic level of the contact angle for a sessile drop. We use a two-dimensional solid-on-solid model to describe the profile of the drop, and the interactions with the substrate are chosen to be of short range. In the presence of a pure substrate
