Interaction picture as any other operator. In particular, let and be the density matrices in the interaction picture and the Schrödinger picture respectively. If there is probability to be in the physical state |"ψ"〉, then Transforming the Schrödinger equation into the interaction picture gives which states that in the interaction picture, a quantum state is evolved by the interaction part of the Hamiltonian as expressed in the interaction picture. If the operator "A" is time-independent (i.e., does not have "explicit time dependence"; see above), then the corresponding time evolution for "A"("t") is given by In the interaction picture the operators evolve in
Types of business entity in Russia can distribute its shares to an unlimited number of shareholders and sell them without limitations. The statutory minimum charter capital is 100,000 Russian roubles. Closed joint-stock company ( (abbreviated ZAO) is a legal entity whose shares are distributed among a limited number of shareholders - maximum 50. The statutory minimum charter capital is 10,000 Russian roubles. In Russia, a JSC can be completely or partially owned by the federal government. Such JSCs are different from another type of state-controlled company, the unitary enterprise. This is a commercial organization that operates state-owned assets. State-owned JSCs do not own or operate any
