Ideal Projections onto Planes
In this paper we classify all ideal projections from C[x, y] onto the linear span of 1, x, y. In particular we show that every such projection is a limit of interpolating projections. That verifies one particular case of a conjecture of C. deBoor. §
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
Polyhedral Surfaces, Polytopes, and Projections
Acknowledgments Many people helped me in miscellaneous ways during the past years in the preparation of this thesis. Thank you for your support! I would like to thank Günter Ziegler for giving me the opportunity to do research in the beautiful environment of " MA 6–2 " at the Technical University. His office door was always open for me when I needed scientific or any other advice. It was a plea...
متن کاملTwo Families of Flag-transitive Affine Planes
Two families of flag-transitive nondesarguesian affine planes of odd order are defined, and isomorphisms among the various planes are studied. Thir ty years ago Wagner [5] proved the impor tan t result that every finite flag-transitive affine plane is a t ranslat ion plane. However , since that t ime relatively few classes of such planes have been found. The purpose of this note is to c o m m e...
متن کاملHeight Functions
Definition 1. An (archimedean) absolute value on a field k is a real valued function ‖ · ‖ : k → [0,∞) with the following three properties: (1) ‖x‖ = 0 if and only if x = 0. (2) ‖xy‖ = ‖x‖ · ‖y‖. (3) ‖x+ y‖ ≤ ‖x‖+ ‖y‖. A nonarchimedean absolute value satisfies the extra condition that (3’) ‖x+ y‖ ≤ max{‖x‖, ‖y‖}. If k is a field, we denote Mk the set of absolute values on k. As an abuse of nota...
