This certainly means reduction of conformal symmetries.Matti Pitkänenhttps://www.blogger.com/profile/13512912323574611883noreply@blogger.comtag:blogger.com,1999:blog-10614348.post-5199838141360941712010-11-04T07:15:01.340-07:002010-11-04T07:15:01.340-07:00Dear Matti

No matter how good their goals are, power corrupts and the worst thing that can happen that one particular ideology wins. <br /><br />One manner to understand finite geometries as opposed to finite-dimensional ones is as geometries with finite number of points satisfying the basic axioms of continuous geometries. Infinite-dimensional geometry is my hobby;-) and its fantastic aspect is that there are very few infinite-dimensional geometries. What one means with pregeometry depends on who defines it.Matti Pitkänenhttps://www.blogger.com/profile/13512912323574611883noreply@blogger.comtag:blogger.com,1999:blog-10614348.post-28972407174386843952010-09-01T13:18:41.828-07:002010-09-01T13:18:41.828-07:00"Geometry is a lifelong hobby especially high..."Geometry is a lifelong hobby especially higher dimensional and Euclidean and finite."<br /><br />Infinite geometry???

I find it uncanny our areas of interest so often coincide before the posting.<br /><br />Your post seems to touch on my view also including your interest to include enquiry into consciousness.<br /><br />The PeSla pesla.blogspot.comL.
