摘要:
In this paper we prove the global existence of the solutions of the Riemann problem for a class of 2 × 2 hyperbolic conservation laws, which is neither necessarily strictly hyperbolic nor necessarily genuinely nonlinear.
摘要:
In this paper we prove that for any prime power q equivalent to 3 (mod 8) there exist 4 - {q(2); k, k, k, k; lambda} supplementary difference sets (SDSs) with k = q(q - 1)/2, lambda 4k - q(2), and Hadamard matrices of order 4q(2), and give several constructions of these SDSs. Moreover, combining the results of reference [1], we conclude that for any prime p equivalent to 3 (mod 8) and integer r greater than or equal to 1 there exists an Hadamard matrix of order 4p(2r).

摘要:
We investigate the growth of the meromorphic function defined by [GRAPHICS] where a(i) are complex numbers, a(i) not equal 0, \a(i)\ greater than or equal to \a(i+1)\(i = 1,2, ...) and lim(1-->infinity) a(i) = 0. b is a complex number.

摘要:
In this paper, it is proved that if A is a normal proper contraction on Hilbert space H and F(z) = U(z) + iV(z) is operator-valued analytic on the unit disc Delta and 0 < p < 1, then parallel to F(A)parallel to(p) less than or equal to parallel to F(0)parallel to(p) + C-p (1 - parallel to A parallel to)(-2) [GRAPHICS]

摘要:
This paper deals with a problem proposed by H. Brezis on the existence of positive solutions to the equation DELTAu + u((n+2)/(n-2)) + f(x, u) = 0 under the Neumann boundary condition D(gamma)u = u((n/(n-2)), where f(x,u) is a lower order perturbation of u((n+2)/n-2)) at infinity.
