Convexity and the Euclidean Metric of Space-Time
We address the reasons why the “Wick-rotated”, positive-definite, space-time metric obeys the Pythagorean theorem. An answer is proposed based on the convexity and smoothness properties of the functional spaces purporting to provide the kinematic framework of approaches to quantum gravity. We employ moduli of convexity and smoothness which are eventually extremized by Hilbert spaces. We point o...
متن کاملBook Review: János Bolyai, Non-Euclidean Geometry, and the Nature of Space, Volume 52, Number 9
This attractive little volume consists of two major components, together with a number of shorter sections. The major components are labeled " Introduction " and " Appendix " respectively , both designations grossly understating their content. The " Appendix " consists of Bolyai's revolutionary tract, with the subtitle " THE SCIENCE ABSOLUTE OF SPACE Independent of the Truth or Falsity of Eucli...
متن کاملCharacterizations of Slant Ruled Surfaces in the Euclidean 3-space
In this study, we give the relationships between the conical curvatures of ruled surfaces generated by the unit vectors of the ruling, central normal and central tangent of a ruled surface in the Euclidean 3-space E^3. We obtain differential equations characterizing slant ruled surfaces and if the reference ruled surface is a slant ruled surface, we give the conditions for the surfaces generate...
