It points out the class of L_r-spaces is the maximal class of range spaces for the closed graph theorem when the class of domain spaces is the class of Mackey spaces with weakly * sequentially complete dual.Some examples are constructed showing that the class of L_r-spaces is strictly larger than the class of separable B_r-complete spaces.Some properties of L-spaces and L_r-spaces are discussed and the relations between B-complete (resp. B_r-complete) spaces and L-spaces (resp. L_r-spaces) are given.展开更多

By applying the conver gence theorem of Coquel-Le Floch [1], the family of approximate solutions defined by the scheme is proven to converge to the unique entropy weak L∞-solution. Furthermore, some numerical experiments on the Cauchy problem for the advection equation and the Riemann problem for the 2D Burgers equation are given and the relatively satisfied result is obtained.展开更多

Driven by the increase of employment and income, in conditions of low inflation and abundant credit, millions of Brazilians have increased in recent years their purchasing power and started to acquire their own home and car--gaudiest symbols of joining the middle class--as well as a wide range of consumer goods. It appears that this set of transformations profoundly altered the perceptions and strategies of social mobility. So this phenomenon is being called the shaping of the new Brazilian middle class. The fact is that there is a group growing, sustained mainly by a decrease in income inequality. In this study, we attempted to draw a clear overview and some disagreements about the emergence of a new Brazilian middle class. On the topic of the emergence of a new Brazilian middle class, one can say that it is not a completely true fact, and that there was actually an expansion of the income of families who still harbor extreme ties with the working classes and why not, popular classes. What to some scholars would be the emergence of a new working class, whose average income is approaching the middle income of what is considered as the lower middle class？展开更多
