How to Recognize a Parabola
Parabolas have many interesting properties which were perhaps more well known in centuries past. Many of these properties hold only for parabolas, providing a characterization which can be used to recognize (theoretically, at least) a parabola. Here, we present a dozen characterizations of parabolas, involving tangent lines, areas, and the well-known reflective property. While some of these pro...
متن کاملParabola - Based Discrete Curvature Estimation †
The local geometric properties such as curvatures and normal vectors play important roles in analyzing the local shape of objects. The result of the geometric operations such as mesh simplification and mesh smoothing is dependent on how to compute the curvatures of meshes, because there is no exact definition of the discrete curvature in meshes. In this paper, we indicate the fatal error in com...
متن کاملThe Calderón Commutator along a Parabola
During the past 30 years, many authors have investigated the L mapping properties of singular integral operators whose “kernels” are actually singular measures supported on lower dimensional subvarieties. One may consult the survey article of Wainger [19] for a history of the subject up to the mid 1980’s. The interested reader may also find a synopsis of more recent developments, along with num...
متن کاملSymmetric Stable Processes in Parabola–shaped Regions
We identify the critical exponent of integrability of the first exit time of rotation invariant stable Lévy process from parabola–shaped region.
متن کاملThe maximum of Brownian motion minus a parabola
We derive a simple integral representation for the distribution of the maximum of Brownian motion minus a parabola, which can be used for computing the density and moments of the distribution, both for one-sided and two-sided Brownian motion .
