# Virtually-asymptotic net

(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)
A net (in differential geometry) on a surface $V _ {2}$ in Euclidean space which, on being deformed somewhat ( $f: V _ {2} \rightarrow V _ {2} ^ {*}$), becomes an asymptotic net of the surface $V _ {2} ^ {*}$. A Voss surface is distinguished by the presence of a conjugate virtually-asymptotic net.
