Question

The poisson bracket {x, p} = −1, then the poisson bracket {x 2 + p, p} is

Answer 1

Answer:

In mathematics and classical mechanics, the Poisson bracket is an important binary operation in Hamiltonian mechanics, playing a central role in Hamilton's equations of motion, which govern the time evolution of a Hamiltonian dynamical system. The Poisson bracket also distinguishes a certain class of coordinate transformations, called canonical transformations, which map canonical coordinate systems into canonical coordinate systems. A "canonical coordinate system" consists of canonical position and momentum variables (below symbolized by {\displaystyle q_{i}} q_{i} and {\displaystyle p_{i}} p_{i}, respectively) that satisfy canonical Poisson bracket relations. The set of possible canonical transformations is always very rich. For instance, it is often possible to choose the Hamiltonian itself {\displaystyle H=H(q,p;t)} {\displaystyle H=H(q,p;t)} as one of the new canonical momentum coordinates.
