Write Torsion Tensor: Definition, Metric Tensor & Equation

Click For Summary
SUMMARY

The discussion centers on the relationship between the torsion tensor and the metric tensor within the context of differential geometry. It establishes that while symmetric Christoffel symbols can be expressed through the partial derivatives of the metric, non-symmetric Christoffel symbols do not have a straightforward definition in terms of the metric. The torsion tensor is determined by the connection, which requires the torsion-free condition to uniquely define a metric-compatible connection. This implies that the torsion tensor is not independent of the metric tensor but rather intricately linked to the choice of connection.

Would it be possible to write the torsion tensor in terms of the metric? I know that a symmetric Christoffel Symbol can be written in terms of the partial derivatives of the metric. This definition of the christoffel symbols does not apply if they are not symmetric. Is it possible to write a definition of the non-symmetric christoffel symbols in terms of a metric, and from that find an equation for the torsion tensor, or is it independent of the metric tensor?

The torsion free condition is required to uniquely define a metric compatible connection. If you let it go, there are several possible metrics (one of which is the torsion free one).
