Dirac equation in the algebra of physical space Dirac equation in the algebra of physical space The Dirac equation, as the relativistic equation that describes spin 1/2 particles in quantum mechanics, can be written in terms of the Algebra of physical space (APS), which is a case of a Clifford algebra or geometric algebra that is based on the use of paravectors. The Dirac equation in APS, including the electromagnetic interaction, reads Another form of the Dirac equation in terms of the Space time algebra was given earlier by David Hestenes. In general, the Dirac equation in the formalism of geometric algebra has the advantage of providing a
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
