Lorentzian circle as a Lie group and a C ∞ action on Lorentz spaces of two dimension
(1999)We define a product on Lorentz circle that is similar to Lorentzian inner product. This product is expanded to Lorents space of two dimension. So we have an C{\infty} action of Lorentz circle on Lorents space of two ... -
