Why We Can Not Surpass Capacity: The Matching Condition
Iterations coding system coding binary input
font style='font-size:12px;'>
2015/8/21
We show that iterative coding systems can not surpass capacity using only quantities which naturally appear in density evolution. Although the result in itself
is trivial, the method which we apply s...

A note on the Triple Product Property subgroup capacity of finite groups
Triple Product Property finite groups Group Theory
font style='font-size:12px;'>
2011/9/23
Abstract: In the context of group-theoretic fast matrix multiplication the TPP capacity is used to bound the exponent $\omega$ of matrix multiplication. We prove a new and sharper upper bound for the ...
