Tóm tắt:

Locally repairable codes (LRCs) are a class of codes which can recover from erasures by accessing a small number of erasure-free code symbols. In this talk, I will give a detailed overview  of Locally repairable codes and also provide detailed properties and constructions of these codes from cyclic codes. Some bounds related with optimality of LRC( Locally repairable Codes) will also be discussed. I will also give an enlightenment of LRC with  complete information of the tradeoff between codewords length, worst case distance, and locality of information symbols. Finally, I will discuss some open problems on Locally repairable Codes.
