Does there exist any 2D surface whose metric tensor is,
##\eta_{\mu\nu}=
\begin{pmatrix}
-1 & 0 \\
0 & 1
\end{pmatrix}##
##\eta_{\mu\nu}=
\begin{pmatrix}
-1 & 0 \\
0 & 1
\end{pmatrix}##
I am looking for a surface in 'space'.Yes. Two-dimensional flat spacetime. Or the worldsheet of a string. What are you looking for in particular?
You mean ordinary space? But you have a Lorentzian signature. Seems to me like looking for complex Majorana spinors.I am looking for a surface in 'space'.
