This result can be seen as part of Penrose and Low's programme intending to describe the causal structure of a space-time M M in terms of the topological and geometrical properties of the space of light rays, i.e., unparametrized time-oriented null geodesics, \mathcal{N} \mathcal{N} ...

We derive the characteristic equations, and the so-called Christoffel equation, for the vector elastodynamic equations in terms of both hypersurfaces of nonuniqueness and as wavefronts based on a physical definition. We follow Courant and Hilbert in defining a wavefront as a surface for which a ...
1. there exists an initial vertex *\in V such that no directed edge ends at *; 2. the map taking finite paths in \mathcal {G} starting at * to G that sends a path with concurrent edges (*,x_1), \ldots ,(x_{n-1},x_n) to \rho (*,x_1)\rho (x_1,x_2) \ldots...
Multiplicity of γ Rays in the Reactions Kr 86 - Sn 120 and Kr 86 - Er 166 The average $\\ensuremath{\\gamma}$-ray multiplicity $M$ has been measured as a function of the scattering angle, energy loss, and nuclear charge of the projectile fragment produced in the $^{86}\\mathrm{...

The illumination terms in the shading must be: Emitted radiance. An “ambient” incident radiance of Lambient=0.05Lambient=0.05 W/(m2 sr). Single-scattered (“direct”) illumination from omni (“point”), spot, and directional sources. If the light is marked to cast shadows, perform...
It is shown that cosmic rays may have caused sufficient ionisation in a solar disc in aKant-von Weizsäcker type of theory about the origin of the solar system to produce a conductivity high enough for magnetohydrodynamic effects to be important. Резюме Показывается, ...
