A Computer Verification of a Conjecture About Erdös-Mordell Curve
Bojan D. Banjac, Branko J. Malesevic, Maja M. Petrovic +1
In this paper we consider Erdös-Mordell inequality and its extension in the plane of triangle to the Erdös-Mordell curve. Algebraic equation of this curve is derived, and using mod…

On the Extension of the Erdos-Mordell Type Inequalities
Branko Malesevic, Maja Petrovic, Marija Obradovic +1
We discuss the extension of inequality R_A >= c/a * r_b + b/a * r_c to the plane of triangle ABC. Based on the obtained extension, in regard to all three vertices of the triangle,…

An application of Groebner bases to planarity of intersection of surfaces
Branko Malesevic, Marija Obradovic
In this paper we use Groebner bases theory in order to determine planarity of intersections of two algebraic surfaces in . We specially considered plane sections of cert…
