Notes on Projective Differential Geometry
Projective differential geometry was initiated in the 1920s, especially by Élie Cartan and Tracey Thomas. Nowadays, the subject is not so well-known. These notes aim to remedy this deficit and present several reasons why this should be done at this time. The deeper underlying reason is that projective differential geometry provides the most basic application of what has come to be known as the ...
متن کاملRecent Developments in Computational Arithmetic Geometry
From 16.05.04 to 21.05.04, the Dagstuhl Seminar 04211 Algorithms and Number Theory was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and i...
متن کاملMetric Connections in Projective Differential Geometry
We search for Riemannian metrics whose Levi-Civita connection belongs to a given projective class. Following Sinjukov and Mikeš, we show that such metrics correspond precisely to suitably positive solutions of a certain projectively invariant finite-type linear system of partial differential equations. Prolonging this system, we may reformulate these equations as defining covariant constant sec...
متن کاملOn some recent developments in Kähler geometry
These are related, because the ideas involved in (1) form one of the main foundations for (2). More precisely, the proof of the Yau conjecture relies on an extension of the partial C estimate to metrics with conic singularities. Gang Tian has made claims to credit for these results. The purpose of this document is to rebut these claims on the grounds of originality, priority and correctness of ...
متن کاملPhytoestrogens: recent developments
Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...
