A negative answer to three questions on $K$-primitive rings

Learning to answer questions

We present an open-domain QuestionAnswering system that learns to answer questions based on successful past interactions. We follow a pattern-based approach to Answer Extraction, where (lexico-syntactic) patterns that relate a question to its answer are automatically learned and used to answer future questions. Results show that our approach contributes to the system’s best performance when it ...

Answer to BT questions

BitTorrent is a P2P file distribution system designed for distributing large files. The current mechanism used to implement BitTorrent does not support streaming of data but with few changes in the protocols of BitTorrent this system can also be used for streaming data. Two important mechanisms which we have to consider while making changes are BT’s Piece selection mechanism and Incentive mecha...

On primitive ideals in polynomial rings over nil rings

Let R be a nil ring. We prove that primitive ideals in the polynomial ring R[x] in one indeterminate over R are of the form I [x] for some ideals I of R. All considered rings are associative but not necessarily have identities. Köthe’s conjecture states that a ring without nil ideals has no one-sided nil ideals. It is equivalent [4] to the assertion that polynomial rings over nil rings are Jaco...
