Pseudosphere

In geometry, a pseudosphere is a surface in R 3 {\displaystyle \mathbb {R} ^{3}} . It is the most famous example of a pseudospherical surface. A pseudospherical surface is a surface piecewise smoothly immersed in R 3 {\displaystyle \mathbb {R} ^{3}} with constant negative Gaussian curvature. A "pseudospherical surface of radius R" is a surface in R 3…
