Abstract. For a two–dimensional time nonlinear hyperbolic equation with a power nonlinearity, a threshold exponent depending on the space dimension is presented. Furthermore, the analysis is extended ...

Mathematics of Computation, Vol. 47, No. 176 (Oct., 1986), pp. 713-727 (15 pages) We show how the Gelfond-Baker theory and diophantine approximation techniques can be ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Somer G. Anderson is CPA, doctor of ...

Here, we show that a circularly polarized emitter (for example, an atom, molecule or classical antenna) near an anisotropic hyperbolic metamaterial slab will unidirectionally emit into extraordinary ...
