On the equivalence to feedforward forms

2003 European Control Conference (ECC), 2003
The problem of (local) coordinates and feedback equivalence of single-input affine nonlinear systems to feedforward forms is studied and solved. The general theory is applied to linear systems, and is illustrated through a simple four dimensional example describing the dynamics of a food-chain.

Equivalence relations, invariants, and normal forms, II

SIAM Journal on Computing, 1984
Summary: For an equivalence relation E on the words in some finite alphabet, we consider the recognition problem (decide whether two words are equivalent), the invariant problem (calculate a function constant on precisely the equivalence classes), the normal form problem (calculate a particular member of an equivalence class, given an arbitrary member)
