inhomogeneous lorentz group造句

• If the spacetime translations are included, then one obtains the " inhomogeneous Lorentz group " or the Poincare group.
• A combination of a rotation with a boost, followed by a shift in spacetime, is an " inhomogenous Lorentz transformation ", an element of the Poincar?group, which is also called the inhomogeneous Lorentz group.
• Notable contributors are physicist E . P . Wigner and mathematician Valentine Bargmann with their Bargmann Wigner programme, one conclusion of which is, roughly, " a classification of all unitary representations of the inhomogeneous Lorentz group amounts to a classification of all possible relativistic wave equations ".
• In this special case, the Hilbert space is a space of irreducible unitary representations of the inhomogeneous Lorentz group ( the Poincar?group ); the S-matrix is the evolution operator between time equal to minus infinity ( the distant past ), and time equal to plus infinity ( the distant future ).
