F. Atiyah formulated a conjecture C1 and later with P. Sutcliffe two stronger conjectures C2 and C3. These conjectures, inspired by physics (spin-statistics theorem of quantum mechanics), are geometrically defined for any configuration of points in the Euclidean three space. The conjecture C1 is proved for n = 3, 4 and for general n only for some special configurations (M.F. Atiyah, M. Eastwood and P. Norbury, D.Djoković). In a lengthy preprint [5] we have verified the conjectures C2 and C3 for parallelograms, cyclic quadrilaterals and some infinite families of tetrahedra. We have also proposed a strengthening of the conjecture C3 for configurations of four points (Four Points Conjectures).(The present author found a new geometric fact for arbitrary tetrahedra and a proof of C2 and C3 for arbitrary four points in the Euclidean three space, but not yet for the hyperbolic case !). A number of conjectures for almost collinear configurations are stated in [5] and proven for n up to nine. In this talk we explain our recent variations of the original conjecture C3 (for almost collinear configurations ) involving naturally exponential matching polynomial inequalities which turn out to be stronger than for the ordinary matching polynomials. \\[0.1cm] {;\bf References and Literature for Further Reading};\\ \newcommand\itm[2]{;\parbox[t]{;1cm};{;#1};\parbox[t] {;14cm};{;#2};\\[1mm] }; \itm{;[1]}; {;Atiyah M, Sutcliffe P, The Geometry of Point Particles. arXiv: hep-th/0105179 (32 pages).
