Making mathematics phenomenal : Based on an Inaugural Professorial Lecture delivered at the Institute of Education, University of London, on 14 March 2012 [PDF]

open access: yes, 2012
Mathematics is often portrayed as an 'abstract' cerebral subject, beyond the reach of many. In response, research with digital technology has led to innovative design in which mathematics can be experienced to some extent like everyday phenomena.

Extreme positive operators on minimal and almost minimal cones

open access: yes, 1982
Fiedler and Pták called a cone minimal if it is n-dimensional and has n+1 extremal rays. We call a cone almost minimal if it is n-dimensional and has n+2 extremal rays.

Eigenpolytope Universality and Graphical Designs

open access: yes, 2023
We show that the eigenpolytopes of graphs are universal in the sense that every polytope, up to affine equivalence, appears as the eigenpolytope of some positively weighted graph. We next extend the theory of graphical designs, which are quadrature rules

Gale duality bounds on the location of roots of polynomials with nonnegative coefficients

open access: yes
We bound the location of roots of polynomials that have nonnegative coefficients with respect to a fixed but arbitrary basis of the vector space of polynomials of degree at most d. For this, we interpret the basis polynomials as vector fields in the real

Estimating the Technical Optimal Scale of Production in Danish Agriculture

open access: yes
This paper uses representative farm account data for 1985-2007 to estimate stochastic production frontiers in the form of input distance functions for Danish crop, dairy and pig farms.

Bounds on the number of real solutions to polynomial equations

open access: yes, 2007
7 pagesInternational audienceWe use Gale duality for complete intersections and adapt the proof of the fewnomial bound for positive solutions to obtain a new bound for the number of non-zero real solutions to a system of n polynomials in n variables ...
