On Napoleon's theorem in the isotropic plane]{On Napoleon's theorem in the isotropic plane

Periodica Mathematica Hungarica, 2006
Napoleon's original theorem refers to arbitrary triangles in the Euclidean plane. If equilateral triangles are externally erected on the sides of a given triangle, then their three corresponding circumcenters form an equilateral triangle. We present some analogous theorems and related statements for the isotropic (Galilean) plane.

On evolutes of curves in the isotropic plane

Aequationes Mathematicae
The Tait-Kneser theorem is a classical theorem which states that the osculating circles along a plane curve with monotone non-vanishing curvature are pairwise disjoint and nested. The main contribution of the paper is to prove a version of this theorem for curves in the isotropic plane.

Kiepert Triangles in an Isotropic Plane

Sarajevo Journal of Mathematics
In this paper the concept of the Kiepert triangle of an allowable triangle in an isotropic plane is introduced. The relationships between the areas and the Brocard angles of the standard triangle and its Kiepert triangle are studied. It is also proved that an allowable triangle and any of its Kiepert triangles are homologic.

Isotropic Plane Elastostatics

2008
We begin with a uniqueness theorem in linear elastic doublet mechanics. With this tool in hand we present two methods of obtaining solutions. The first stems from a correspondence between problems in doublet and continuum mechanics which allows the generation of a solution in one theory given a solution in the other.

Thébault’s Pencil of Circles in an Isotropic Plane

Sarajevo Journal of Mathematics
In the Euclidean plane Griffiths's and Thébault's pencil of the circles are generally different. In this paper it is shown that in an isotropic plane the pencils of circles, corresponding to the Griffiths's and Thébault's pencil of circles in the Euclidean plane, coincide.

Wrinkling of Plane Isotropic Biological Membranes

Journal of Applied Mechanics, 2006
The problem of the wrinkling of plane isotropic membranes characterized by a Fung type constitutive model in biaxial tension has been formulated and solved within the framework of finite strain hyperelasticity. The formulation follows the approach of Pipkin [Pipkin, A.C., 1986, IMA J. Appl. Math., 36, pp. 85–99; 1994, ibid., 52, pp.

On Foci and Asymptotes of Conics in the Isotropic Plane

Sarajevo Journal of Mathematics
The paper shows that every conic with foci in the isotropic plane can be represented by the equation of the form $y^2=\epsilon x^2+x$, where $\epsilon \in \{-1, 0, 1\}$ for an ellipse, a parabola and a hyperbola with foci respectively. Using this equation some important properties of the foci are proved.
