Abstract:
We first prove that the numbers of integer partitions satisfy a system of homogeneous linear equations. Then we derive an explicit formula for the coefficients of the Euler product function in terms of the number of insets. As a consequence, we express the Euler pentagonal number theorem in terms of insets.
Finally, we derive an explicit formula for the entries of the Mahonian triangle.
