Kenneth J. Falconer

from Wikipedia, the free encyclopedia

Kenneth John Falconer (* 1952 ) is a British mathematician who mainly deals with fractal geometry , geometric measurement theory and combinatorial geometry. He is a professor at St. Andrews University . In 2018 he was appointed Regius Professor of Mathematics to succeed Igor Rivin .

Falconer studied at Cambridge University , where he received his doctorate from Hallard Croft in 1979 ( Properties of Convex Sets and Functions Determined by Sectional Integrals ). He was a lecturer and reader at the University of Bristol before becoming a professor at St. Andrews in 1993.

It deals with geometric properties (such as values ​​of dimension) fractal sets, such as B. occur in dynamic systems. In 1987 he proposed the existence of a digital sundial, sets that allow projections in any direction ( popularized by Ian Stewart ). He studied random processes (such as percolation ) and nonlinear partial differential equations on fractals. Falconer's unsolved conjecture says: if a compact subset S of the d-dimensional Euclidean space of a Hausdorff dimension is greater than , then the set of distances between points in S has positive Lebesgue measure .

In 1999 he organized a month-long program on fractals at the Isaac Newton Institute . He was visiting professor at Oregon State University and the Australian National University , among others .

In 1998 he became a Fellow of the Royal Society of Edinburgh .

He is co-editor of Advances in Mathematics and Fractals.
