An elementary construction of Khovanov-Rozansky type link homology
elementary construction Khovanov-Rozansky type link homology
2011/2/22
In this article, we give an elementary construction of sl(n)-homological invariants of links presented by braid forms. The Euler characteristic of this complex is equal to sl(n) quantum polynomial inv...
Gaussian Broadcast Channels with an Orthogonal and Bidirectional Cooperation Link
Gaussian Broadcast Channels Orthogonal Bidirectional Cooperation Link
2010/11/24
This paper considers a system where one transmitter broadcasts a single common message to two receivers linked by a bidirectional cooperation channel, which is assumed to be orthogonal to the downlin...
Network error correction with unequal link capacities
Network error correction unequal link capacities
2010/11/22
This paper studies the capacity of single-source single-sink noiseless networks under adversarial or arbitrary errors on no more than z edges. Unlike prior papers, which assume equal capacities on al...
Overlay Protection Against Link Failures Using Network Coding
Overlay Protection Link Failures Network Coding
2010/11/22
This paper introduces a network coding-based protection scheme against single and multiple link failures. The proposed strategy ensures that in a connection, each node receives two copies of the same ...
