In this paper, using the representation theorem of Moisil (see [2]) the author introduces and examines the concept of representability of Lukasiewicz algebras. The results and notations used are from [1], [2]. 相似文献

It is argued that although the pathological multiplicity of Nash equilibria of super games stated by the folk theorem can be removed by introducing limited observations into super games with a continuum of players, the consideration of super games in terms of the Nash equilibrium concept involves a more fundamental and conceptual difficulty. 相似文献

Some remarks on a strict minimax inequality, which plays a fundamental role in Ricceri's three critical points theorem, are presented. As a consequence, some recent applications of Ricceri's theorem to nonlinear boundary value problems are revisited by obtaining more precise conclusions. 相似文献

We provide an infinite dimensional version of Rademacher's theorem in a linear space provided with a bounded Radon measure . The underlying concepts of the Lipschitz property and differentiability hold -almost everywhere and only in the linear subspace of directions along which is quasiinvariant. The particular case where (X, ) is the Wiener space (and for which the subspace of quasiinvariance coincides with the Cameron-Martin space) was proved in Enchev and Stroock (1993).Partially supported by the fund for promotion of research at the Technion. 相似文献

In this paper we give a complete answer to a question which naturally arises in comparing classical results of F. E. Browder and K. Fan on sets with convex sections with a recent result of B. Ricceri on sets with connected sections. 相似文献

LetW(k, 2) denote the, least numbers for which the system of equations
has a solution with

2(logk+loglogk+O(1)), and moreover that whenK is large, one hasW(k, 2)1/2k(k+1)+1 for at least one valuek in the interval [K, K
3/4+]. We show also that the leasts for which the expected asymptotic formula holds for the number of solutions of the above system of equations, inside a box, satisfiessk

It is shown that if a certain condition on the variances of the partial sums is satisfied then a theorem of Philipp and Stout, which implies the asymptotic fluctuation results known for independent random variables, can be applied to some quantities related to continued fractions. Previous results on the behavior of the approximation by the continued fraction convergents to a random real number are improved.

Let (X,μ, T) be an ergodic dynamic system and let ξ = (C1, C2, ...) be a discrete decomposition of X. Conditions are considered for the existence almost everywhere of $$\mathop {\lim }\limits_{n \to \infty } \frac{1}{n}\left| {\log \mu (C_{\xi ^n } (x))} \right|,$$ whereC ξn(x) is the element of the decomposition ξn = ξ V T ξ V ... < Tn-1ξ containing x. It is proved that the condition H(ξ) < ∞ is close to being necessary. If T is a Markov automorphism and ξ is the decomposition into states, then the limit exists, even if H(ξ) = ∞, and is equal to the entropy of the chain. 相似文献
