Are cartesian coordinates the only coordinates with a holonomic basis that's orthonormal everywhere?
The discussion centers on the properties of Cartesian coordinates, specifically their holonomic basis and orthonormal characteristics. It is established that Cartesian coordinates, defined by the basis vectors ##e_i = \delta _i^j##, possess a holonomic basis that is orthonormal throughout the entire space. The conversation emphasizes the uniqueness of Cartesian coordinates in this context, suggesting that other coordinate systems may not share these properties.
PREREQUISITESMathematicians, physicists, and students studying advanced calculus or differential geometry who are interested in the properties of coordinate systems and their applications in various fields.
I would assume rectangular coordinates with basis ##e_i = \delta _i^j##martinbn said:How do you define cartesian coordinates?
