circle_bundles.Torus_KleinQuotientMetric_R4(*, base_in='z2')

Z2 quotient metric on R^4 C^2-torus embedding that implements the Klein identification (base,fiber) ~ (base+pi, -fiber) with an explicit base-factor choice.

base_in:

• “z1” (default): base angle is encoded in z1

• “z2”: base angle is encoded in z2

Parameters:

base_in (str)

Return type:

Metric
