In this article we establish new inequalities, both conditional and unconditional, for the restriction problem associated to hyperbolic, or one-sheeted, hyperboloid in three dimensions, endowed with a Lorentz-invariant measure. These inequalities are unconditional (and optimal) bilinear range q>103. Nous obtenons des nouvelles inégalités pour le problème de la transformée Fourier associé à l'hy...

Gangrene of the skin is a very rare complication of chickenpox. Barenberg and Lewis (1927) saw one example in over 2,000 children and Wishik and Bullowa (1935) saw four examples in 2,534 children with chickenpox. The condition was probably first described by Stokes (1807), but was first discussed in some detail by Jonathan Hutchinson in 1882. The latter's paper is notable for the beautiful repr...
