Convex Sequence and Convex Polygon
Angshuman Robin Goswami, István Szalkai
In this paper, we deal with the question; under what conditions the points form a convex polygon provided holds. One of the ma…
On contact numbers of locally separable unit sphere packings
Károly Bezdek
The contact number of a packing of finitely many balls in Euclidean -space is the number of touching pairs of balls in the packing. A prominent subfamily of sphere packings is f…
Constructing and Understanding New and Old Scales on Slide Rules
Istvan Szalkai, Ace Hoffman
We discuss the practical problems arising when constructing any (new or old) scales on slide rules, i.e. realizing the theory in the practice. This might help anyone in planning an…
On the General Shape of Scales on Slide Rules
Istvan Szalkai
We give a thoroughful explanation of the general properties of different, general scales, corresponding to different (all possible) mathematical functions f(x), we mention and anal…
General Two-variable Functions on the Slide-rule
István Szalkai
We discuss the general theory of realizing two-variable fuctions on slide rules (based on our paper 1977) and offer some new scales for practical use.
