It realizes the sublation of theory and ideology by means of critical, explanatory and constructive logic, displaying a unique theoretical originality. Lenin＇s theory of imperialism offers a theoretical reflection on the development of capitalism and its historical trends; it is a practical response to the world structural contradictions arising from imperialism, an epochal reflection that vigorously explores and constructs the value claims of a new civilization and provides in-depth Marxist view of world history. The methodology and general principles of Lenin＇s study of imperialism are based on the materialist view of history. They are not out of date, nor are the propositions in his theory of imperialism, based as they are on research into monopoly. At the same time as it declared war on the values, systems and practices of the old world, Lenin＇s theory provided a completely new cognitive method, philosophical attitude and ideal values for the future society. This has become the precious wealth of mankind, wealth that transcends historical time and space.展开更多

By introducing a partially expo- nential quasi-monotonicity condition and a new cross iteration scheme, we reduce the existence of traveling wave solutions to the existence of a pair of upper-lower solutions. By constructing a desirable pair of upper-lower solutions, we establish the existence of traveling wave solutions. Finally, some numerical examples are carried out to illustrate the theoretical results.展开更多
