COMPLEX SOLUTIONS TO QUADRATIC INEQUALITIES AND THEIR MODELING BY MEANS OF
Many people think that inequalities cannot be considered over the field \(\mathbb{C}\) of complex numbers. And really, on \(\mathbb{C}\) does not possess an order to make it an ordered field. But other orders exist and can be successfully used for getting an...

SETS OF NON-SELF-INTERSECTING PATHS CONNECTING THE VERTICES OF A CONVEX POLYGON
The paper deals with counting the sets of non-self-intersecting paths whose nodes form a partitioning of the set of vertices of a given convex polygon. There turn to exist compact formulae when the magnitude of these sets is fixed. Some of these formulae provi...
