#### A Korovkin theorem for AL-spaces

(University of Canterbury. Dept. of Mathematics, 1982)

#### Takenings, rames and mills : structures for the modelling of branching

(University of Canterbury. Dept. of Mathematics, 1987)

A takening is a combinatorial structure composed of points and rays. A ray is a finite sequence of at least two points, and two rays have at most one point in common, which must be the foot (initial point) of at least ...

#### Doubly-periodic progressive permanent waves in deep water

(University of Canterbury. Dept. of Mathematics, 1984)

The Stokes wave is generalized to progressive waves in deep water which are periodic in two orthogonal directions, and are steady relative
to a frame of reference moving in one of these directions. These doublyperiodic
...

#### Existence and uniqueness of algebraic function approximations

(University of Canterbury. Dept. of Mathematics, 1989)

The problem of approximating a real-valued, locally analytic function, f(x), by an algebraic function, Q(x) is considered. Existence and uniqueness theorems are obtained
under fairly general conditions, including those ...

#### Oblique wave groups in deep water

(University of Canterbury. Dept. of Mathematics, 1982)

Oblique wave groups consist of waves whose straight parallel lines of constant phase are oblique to the straight parallel lines of constant
phase of the group. Numerical solutions for periodic oblique wave groups
with ...

#### A digital logic simulator for the Apple Macintosh

(University of Canterbury, 1985)

The aim of this project was to design a digital logic simulator to run on the Apple Macintosh. It was envisaged that users would be able to design a network of gates, flip-flops and signal sources interactively, then ...

#### The L∞ exact penalty function in semi-infinite programming

(University of Canterbury. Dept. of Mathematics, 1989)

An algorithm for semi-infinite programming using sequential quadratic programming techniques together with an L∞ exact penalty function is presented, and global convergence
is shown. An important feature of the convergence ...

#### Steady state simulation of queueing processes : a survey of problems and solutions

(University of Canterbury, 1988)

For years computer-based stochastic simulation has been a commonly used tool in the performance evaluation of various systems. Unfortunately results of some studies can be given little credibility, since they are presented ...

#### Univariate multiquadric approximation : reproduction of linear polynomials

(University of Canterbury. Dept. of Mathematics, 1989)

It is known that multiquadric radial basis function approximations can reproduce low order polynomials when the centres form an infinite regular lattice. We make a start
on the interesting question of extending this ...

#### Space-like infinity and asymptotic photon fields in Q.E.D

(University of Canterbury. Dept. of Mathematics, 1982)

Infra-red effects in Q.E.D. are discussed from the point of view of space-like infinity. Using the properties of spin and conformally weighted functions defined on a null
cone, an elementary proof of the infra-red coherence ...
