The fault diagnosis, which is the process of identifying fault processors in a multiprocessor system through testing. The conditional diagnosis requires that for each processor u in a system, all the processors that are directly connected to u do not fail at the same time. In this paper, we study the conditional diagnosability of the n-dimensional locally twisted cubes. After showing some properties of the locally twisted cubes, we prove that it under the PMC model is 4n ¨C 7 for n ¡Ý 5. %K Locally Twisted Cubes %K Diagnosability %K Conditional Diagnosability %K PMC Mode %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=8469
