thx for help

OH A system is described by a complex variable a(t) and the equation of motion ia = where Ha, a*] is some da* OH OH function. In terms of a new variable b = b(a) , the equation of motion takes on the form ib = + Which of the ab following statements are correct? Select one or more: O 1. {b, b' } = i. O 2. The variable b is canonical. O ab da* ab da da da* O OA OB OA OB OA OB OA OB 4. For two functions A and B of the variables, da da* da* da ab ab+ ab* ab O 5. The function H [b, b* ] is a constant of motion
