本书主要研究满足开集条件的自相似集的结构，从Hausdorff测度和上凸密度的计算与估计到其内部结构的理论研究，都作了比较全面的阐述．全书共分四章。章介绍基本定义、符号和基本命题；第2章讨论自相似集；第3章讨论上凸密度；第4章讨论自相似集的结构及相关问题．两个附录分别介绍了集合论、点集拓扑和测度论的基础知识。 本书可作为高等院校分形几何方向研究生、教师的教学用书，也可供相关方向科研人员和工程技术人员阅读参考。
The book is a continuation of development of" Boundary value problems for nonlinear elliptic equations and systems" and "Linear and quasilinear equations of hyperbolic and mixed types ".A large portion of the work is devoted to boundary value problems for general elliptic plex equations of first,second and fourth order,initial-boundary value problems for nonlinear parabolic plex equations of first and second order.Moreover,some results about first and second order plex equations of mixed (elliptic-hyperbolic) type are investigated .Applications of nonlinear plex analysis to continuum mechanics are also introduced.
