My understanding is that extra space dimensions are added in a way such that the line element in flat spacetime is calculated by the Pythagorean theorem: $$ds^2=-c^2dt^2+dx_1^2+dx_2^2+dx_3^2+dx_4^2+...+dx_n^2$$ Now I...

1 answerI have a scalar complex field: $phi(x) = phi_{1} + i phi_{2};$ so $;phi^{*}(x) = phi_{1} - i phi_{2}$ where $phi_{1}, ; phi_{2}$ are real scalar...
