Introduction: Davrin
I'm a retired pharmacist living in Melbourne, Australia
I've been studying and researching mathematics as a passionate interest for the last 30 years,
I have great interest in several disparate areas of mathematics, especially geometry, including Fractals, Intrinsic (Natural) Plane Geometry, Osculants &
Glove-Osculants, and their multitudinous Orders-Of-Contact, (including their recursive series), Calculus of Variations in the Plane, Anallagmatic Curves
(Self-inverters), Absolute Invariants of the General Quadratic Form in many planar coordinate frameworks as well as an analysis of these quadratic forms,
Pursuit (& Pseudo-Pursuit) Curves in closed form, Fractran (al la John Horton). The Reciprocal System of Physical Theory (al la Dewey B. Larson), Newton's
Equations of Motion in extended form, Gyroscopic motion,(including the actual spinning motion of atoms and subatomic particles), River Meander and Elastica
Curves, Circular Asymptotes, Angle of Contingency and its many applications, Fractional Derivatives, Deviation (Aberration) of plane curves, Iterates and
Semi-Iterates, Sand Dunes.
Some of my software is Fractint for the fractals and Derive XM and Derive for Windows as mathematical assistants for just about any type of maths
problem as well as plotting graphs.
I've had a strong interest in several aspects of fractals for many years, back from the days of DOS, hence the use of Fractint.
Because of the infinite variety of contrived fractals, that can be generated by the multitude of software around, I decided to limit my interest to
those fractals, that can be generated solely by an input equation of a a plane curve. This facility is made available by Fractint. (I don't know if
any other software can do this, I hope that there is, since working in DOS is very limiting.)
This led me to discover the work of Hans Lauwerier and his partially-explained method of predicting the basin of stability. The classic example,
that he used, proved that the Mandelbrot, being generated by inputting the equation to a circle, results in a cardioid basin of stability.
This led me to investigate other plane curves being inputted and hopefully predict their particular basins of stability
I have written a paper in WordPerfect, (involving equations and graphs), that I have converted to both HTML and PDF. If any reader is interested in this
maths of fractals, I can provide a copy of my findings so far, and hopefully more development may be facilitated.
Hey there, David Halprin !! Welcome to this particular Forum.
