摘要: Words and finite automata over words are central notions in computer science. They model the sequential executions of systems. However, both world its own science have to cope with another phenomenon as well: concurrency. Then not all events be ordered but some actions may appear independently. On other hand, can seen one-dimensional objects, higher-dimensional objects like two-dimensional rectangles or pictures handled well. This chapter is concerned weighted that describe quantitative aspects partially sets pictures. More specifically, we first consider asynchronous cellular compute semiring valuations Mazurkiewicz traces. In a similar spirit, branching associate weights series-parallel pomsets. Thirdly, picture arrays colors. We characterize expressive power these by rational expressions monadic second-order logics.
