On Expanding Endomorphisms of the Circle
Journal of the London Mathematical Society, 1990A problem posed by M. Shub and D. Sullivan on the classification of real Lebesgue measure-preserving endomorphisms of the circle is investigated. A new Jacobian invariant is introduced and complete measure-theoretic isomorphism invariants are given which are simultaneously measure-theoretic and topological in character.

On the Endomorphisms of a Polynomial Ring
Canadian Journal of Mathematics, 1976This paper arises in the attempt to solve the following problem related to the Zariski Problem. Let A be a polynomial ring in three variables over a field, . Suppose there is a subring B of A such that k ⊆ B and there is variable t over B such that B[t] = A. Then is it true that B is a polynomial ring over k?

Unitary and Normal endomorphisms
2007Unitary endomorphisms of an inner product space are introduced and studied. In particular, unitary and orthogonal matrices are considered. Many examples are considered, among them Householder matrices and special orthogonal matrices. Unitarily-similar matrices are defined and Schur’s Theorem is proven. Normal endomorphisms of an inner product space are
