Pseudo - Incircles Stanley

چکیده
This paper generalizes properties of mixtilinear incircles. Let (S) be any circle in the plane of triangle ABC. Suppose there are circles (Sa), (Sb), and (Sc) each tangent internally to (S); and (Sa) is inscribed in angle BAC (similarly for (Sb) and (Sc)). Let the points of tangency of (Sa), (Sb), and (Sc) with (S) be X, Y , and Z, respectively. Then it is shown that the lines AX, BY , and CZ meet in a point.

We consider a dissection problem of a regular n-sided polygon that generalizes Suzuki’s problem of four congruent incircles in an equilateral triangle.
متن کاملOn a special class of Stanley-Reisner ideals
For an $n$-gon with vertices at points $1,2,cdots,n$, the Betti numbers of its suspension, the simplicial complex that involves two more vertices $n+1$ and $n+2$, is known. In this paper, with a constructive and simple proof, wegeneralize this result to find the minimal free resolution and Betti numbers of the $S$-module $S/I$ where $S=K[x_{1},cdots, x_{n}]$ and $I$ is the associated ideal to ...

The notion of peace, regardless of theorizations accepted in th field and since the Enlightenment Period, and the era known as Modernism, has, constantly, been one of the challenges of mankind, and also scientists in the field of political sciences and international relations. Contrary to the presentation of the idea of peace and respect to the human rights in some of the fore...
متن کاملUbiquitous Archimedean Circles of the Collinear Arbelos
For a point O on the segment AB in the plane, the area surrounded by the three semicircles with diameters AO, BO and AB erected on the same side is called an arbelos. It has lots of unexpected but interesting properties (for an extensive reference see [1]). The radical axis of the inner semicircles divides the arbelos into two curvilinear triangles with congruent incircles called the twin circl...
متن کاملDe novo SVM classification of precursor microRNAs from genomic pseudo hairpins using global and intrinsic folding measures
MOTIVATION MicroRNAs (miRNAs) are small ncRNAs participating in diverse cellular and physiological processes through the post-transcriptional gene regulatory pathway. Critically associated with the miRNAs biogenesis, the hairpin structure is a necessary feature for the computational classification of novel precursor miRNAs (pre-miRs). Though many of the abundant genomic inverted repeats (pseudo...
