The Hardy space Hpis not locally convex if 0 < p < 1, even though its conjugate space(Hp) separates the points of Hp. But then it is locally p-convex, and its conjugate cone(Hp) p is large enough to separate the points of Hp. In this case, the conjugate cone can be used to replace its conjugate space to set up the duality theory in the p-convex analysis. This paper deals with the representation problem of the conjugate cone(Hp) p of Hpfor 0 < p ≤ 1, and obtains the subrepresentation theorem(Hp) p L∞(T, C p).

By applying the mastersymmetry of degree one to the time-independent symmetry K_(1), the fifth-order asymmetric Nizhnik-Novikov-Veselov system is derived. The variable separation solution is obtained by using the truncated Painlevé expansion with a special seed solution. New patterns of localized excitations, such as dromioff, instanton moving on a curved line, and tempo-spatial breather, are constructed. Additionally, fission or fusion solitary wave solutions are presented,graphically illustrated by several interesting examples.

In a paper published in Acta Mathematica Sinica(2016, 59（4）) we obtained some representation theorems for the conjugate spaces of some ltype F-normed spaces. In this par per, for a sequence of normed spaces {X}, we study the representation problems of conjugate spaces of some l（{X}） type F-normed spaces, obtain the algebraic representation continued equalities(l（{X）)*A=(c（{X}）)*A=c（{Xi*}）,(L（X）)*A=(c（X）)*A=(c（X）)*A=(c（X）)*A=C（X*）,and the topological representation((c（{X}）)*,sw*) = c（{X*}）,where sw* is the sequential weak star topology. For the sequences of inner product spaces and number fields with the usual topology, the concrete forms of the basic representation theorems are obtained at last.

With the rapid and continual growth of national economy, the gap between oil demand and supply keeps widening in China, therefore China will increasingly depend on imported oil. However, the world＇s oil and gas resources are unevenly distributed; global world＇s oil prices remain high; and over 70 percent of China＇s imported oil has to be shipped through the Malacca Strait. There are various ways to ensure China＇s oil security today, and the practical and feasible strategic option is to increase the discovery and production of domestic oil, raise energy efficiency and develop petroleum substitutes. Scientific and technological innovation is crucial both in new oil reserves discovery and production, energy conservation, and in the development of petroleum substitutes, establishment of a strategic oil reserve system and for environment protection. This indicates that China should take effective measures in investment strategy, fiscal policies, financing instruments, intellectual property protection, fostering talents and professionals, so as to establish its own scientific and technological innovation system in the petroleum industry and be better able to ensure oil security.
