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 be public and nonpublic, but not Closed or Open. Public Joint-stock is like an OAO (shares are publicly traded). Moreover, it is important to have the word "public" in the Name of the Company (ПAO, PAO). All companies which were ЗАО become OOO and have to correct the type of Company in their founding documents (charter). The statutory minimum charter capital is 5000 Russian minimum wage rates (in 2014 1 minimum wage rate is 5554 roubles) Open joint-stock company ( (abbreviated OAO) is a legal entity where shares may be publicly traded without the permission of other shareholders.
