This quantity provides easy-to-understand but impressive homes acquired utilizing topological, geometric and graph theoretic instruments within the components coated through the Geometry convention that happened in Mulhouse, France from September 7–11, 2014 in honour of Tudor Zamfirescu at the social gathering of his seventieth anniversary. The contributions deal with topics in convexity and discrete geometry, in distance geometry or with geometrical taste in combinatorics, graph concept or non-linear research. Written by means of most sensible specialists, those papers spotlight the shut connections among those fields, in addition to ties to different domain names of geometry and their reciprocal impact. they give an summary on contemporary advancements in geometry and its border with discrete arithmetic, and supply solutions to numerous open questions. the quantity addresses a wide viewers in arithmetic, together with researchers and graduate scholars drawn to geometry and geometrical problems.

Moreover, if uθ u θ [ uu ] θ ] = 0, then u = u > 2; if [ uuθ ] ≥ 1, then u ≥ [ u ]+1 ≥ 21 u θ > uθ u θ . Now we dissect R into [ uuθ ] + 1 rectangles with sides 1 and convenience,√ we denote such√ a rectangle by Ru . [ uuθ 1. Hence 1 < u < u. For the sake of If u ∈ (1, 2) (resp. 1 Ru admits an acute triangulation T Ru such that |T Ru | = 16 (resp. |T Ru | = 8) and δT Ru ≥ θ . Putting these acute triangulations together, we obtain the desired result. 3 Ru admits a non-obtuse triangulation T Ru such that |T Ru | = 8 and δT R > θ .
