Inflection Points [President’s Message]
نویسندگان
چکیده
Sometimes history is a Morse function. Inflection points arrive, unanticipated, and in the blink of an eye, present reality our expectations for future are redefined. The assassinations John F. Kennedy Martin Luther King Jr. 1960s, Tiananmen Square fall Berlin Wall 1989, World Trade Center attacks 2001—all occupied mere seconds, minutes, or, at most, few days; each changed trajectory history.

Inflection Points, Extatic Points and Curve Shortening
As the name suggests, Curve Shortening is a gradientflow for the length functional on the space of immersed curves in the surfaceM. One can therefore try to use Curve Shortening to prove existence of geodesics by variational methods. In my talk at S’Agarro I observed that geodesics always are curves without self-tangencies, and recalled that the space of such curves has many different connected...
متن کاملInflection points and singularities on C-curves
We show that all so-called C-curves are affine images of trochoids or sine curves and use this relation to investigate the occurrence of inflection points, cusps, and loops. The results are summarized in a shape diagram of C-Bézier curves, which is useful when using C-Bézier curves for curve and surface modeling. 2003 Elsevier B.V. All rights reserved.
متن کاملTransformed density rejection with inflection points
The acceptance-rejection algorithm is often used to sample from non-standard distributions. For this algorithm to be efficient, however, the user has to create a hat function that majorizes and closely matches the density of the distribution to be sampled from. There are many methods for automatically creating such hat functions, but these methods require that the user transforms the density so...
متن کاملInflection points of coherent reliability polynomials
Examples of coherent reliability polynomials with more than one inflection point are given. They are created by examining the structure of a reliability polynomial using a convex basis.
متن کاملInflection Points on Real Plane Curves Having Many Pseudo-Lines
A pseudo-line of a real plane curve C is a global real branch of C(R) that is not homologically trivial in P(R). A geometrically integral real plane curve C of degree d has at most d− 2 pseudo-lines, provided that C is not a real projective line. Let C be a real plane curve of degree d having exactly d − 2 pseudo-lines. Suppose that the genus of the normalization of C is equal to d− 2. We show ...
