The critique of the traditional foundations of mathematics reveals a number of errors including inconsistency (contradiction or paradox) and undefined and vacuous concepts which fall under ambiguity. Critique of the real and complex number systems reveals similar defects all of which are responsible not only for the unsolved long standing problems of foundations but also of traditional mathematics such as the 379-year-old Fermat’s last theorem (FLT) and 274-year-old Goldbach’s conjecture. These two problems require rectification of these defects before they can be resolved. One of the major defects is the inconsistency of the field axioms of the real number system with the construction of a counterexample to the trichotomy axiom that proved it and the real number system false and at the same time not linearly ordered. Indeed, the rectification yields the new foundations of mathematics, constructivist real number system and complex vector plane the last mathematical space being the rectification of the complex real number system. FLT is resolved by a counterexample that proves it false and the Goldbach’s conjecture has been proved both in the constructivist real number system and the new real number system. The latter gives to two mathematical structures or tools—generalized integral and generalized physical fractal. The rectification of foundations yields the resolution of problem 1 and the solution of problem 6 of Hilbert’s 23 problems.展开更多

They show that under some assumptions, each equilibrium P-i splits into two equilibria <(P)over tilde (i)> and P-i(alpha), i = 0, 1, and find the Melnikov vector conditions assuring the existence of a heteroclinic orbit from P-1(alpha) to P-0(alpha) along directions that are tangent to the strong unstable (resp.strong stable) manifold of P-1(alpha) (resp.P-0(alpha)). The exponential trichotomy and the unified and geometrical method are used to prove their results.展开更多

In 1990, Avenue was short-listed for the Miles Franklin Prize but failed to win this Australian national award. Judged by Chinese semiotician Zhao Yiheng's reception model of narratives, this is a "message blocked" case. Using the framework of Roman Jakobson's communication model, this paper reinterprets the six constitutive factors and functions to investigate the elements that blocked the message. My main argument is that "contact", "context", and "code" jointly blocked the communication; the three Cs reflect three long-standing problems in Australian literature: the issue of cultural identity, the dark side of White Australian Dream, and the Orientalist representation of "the other" culture. The failure in literary communication analyzed also suggests that Wally's perception of China follows a Saussurean dichotomy which presupposes a closed linguistic system and excludes the role of the subject and the extra-semiotic object in signification. The Peircean trichotomy better captures the process of concept formation and is a better approach to transcultural writing in the contemporary postmodern situation. Transcultural writing challenges its readers; we need to transcend our confined nationality and persistent prejudice, and develop adequate "transnational literacy" to appreciate this new form of cultural production.展开更多
