THIS RESEARCH WAS PARTIALLY SUPPORTED BY THE JOHN TEMPLETON FOUNDATION.

**********************************************************************

Recall that in Integer Decomposition Theory 3 http://www.cs.nyu.edu/pipermail/fom/2010-April/014646.html 
  we used the following notion of integer decomposition:

An E decomposition of n takes the form

n = m_1 + ... + m_k

where (m_1,...,m_k) in E and 0 <= m_1,...,m_k < n.

We realized that this was too strong. So in the most recent Integer  
Decomposition Theory 4 http://www.cs.nyu.edu/pipermail/fom/2010-April/014662.html 
  we used the following more general notion of integer decomposition:

An f decomposition of n takes the form

n = f(m_1,...,m_k)

where 0 <= m_1,...,m_k < n.

This raises the question of just what notions of integer decomposition  
can be used.

Instead of going all the way to f decompositions, we can modify the  
notion of E decomposition as follows.

***An E decomposition of n takes the form

n = the alternating sum of m_1,...,m_k; i.e.
n = m_1 - m_2 + ... +- m_k

where (m_1,...,m_k) in E and 0 <= m_1,...,m_k < n.***

With this strengthening of the definition of E decomposition, the  
results claimed in Integer Decomposition Theory 3 go through.
