The following notes are the outcome of a course of lectures to pupils on invariants. The methods are new to me, but I publish them with hesitation and apologise beforehand should they prove well known.

On Chords of a Conic which touch Another Conic
The Mathematical Gazette, 1940A closed conic C is completely contained inside a closed conic S . From any point 1 on S we draw a tangent 1, 2 to C meeting S again ...

Conics which touch five given Conics
The Mathematical Gazette, 1948In these days of examinations and syllabuses it is perhaps not superfluous to remind teachers of the maxim that they ought to teach more than their pupils need to learn. To be an expert on circles it is necessary to study other conics, and to appreciate homographies it is as well to know something about other correspondences.

An elementary notion of geometry, the concept of Gergonne point is generalized in this paper. Given a triangle $V_1V_2V_3$, a point $I$ and three arbitrary directions $q_i$, we find a distance $x=IQ_1=IQ_2=IQ_3$ along these directions, for which the three cevians $V_iQ_i$ are concurrent. If $I$ is the incenter, $q_i$ are the direction of the altitudes,

Portfolios are designed to maximize a conservative market value or bid price for the portfolio. Theoretically this bid price is modeled as reflecting a convex cone of acceptable risks supporting an arbitrage free equilibrium of a two price economy.
