Abstract

The author of CST addresses similar issues head on, jumping right in from Riemann's I Habilitation i lecture by introducing the metric I g i as a I line element i Graph HT ds2= i,jgijdyidyj ht , first for Euclidean space and then for spheres and finally, as a harbinger of what's to come, for the projective plane. The local version discussed in the text is the classical equation Graph HT TKdA= i=13 i- , ht relating total curvature of a geodesic triangle I T i to its angle defect. Stavrov calls this PDE a I relativistic Poisson equation i , and one seeks a positive solution Graph HT 0 ht . [Extracted from the article]

2. SKYWORTH W82 65”.

Author

JACOBI, JON L.

Subjects
*CURVATURE, *WIRELESS Internet
Abstract

Skyworth.net Skyworth's TV is described as "transformable", by which the company means the TV's curvature is adjustable, from flat to 1,000R. Curvature rat-ings - 1,000R, in this case - define the distance in millimeters that the viewer can sit and still see the entire display properly. he lower the number, the greater the curve. The back of the W82 features 37 pieces in a shell that fit like scales and adjust as the motor changes the display's curvature. Beyond that, the W82 is a 10-bit, 120Hz panel featuring Dolby Vision, HDR10, and Wi-Fi 6 connectvity. [Extracted from the article]
