Metaplectic Correction

Definition

Metaplectic correction refers to a process in symplectic geometry that allows one to address certain anomalies in the quantization of symplectic manifolds. This correction is essential when transitioning from classical mechanics to quantum mechanics, ensuring that the quantized systems reflect the underlying symplectic structure. It plays a vital role in various applications, particularly in the context of phase space and the quantization of physical systems, helping to bridge the gap between the mathematical framework and physical reality.
