Pentagonal theorem

The theorem can be interpreted combinatorially in terms of partitions. In particular, the left hand side is a generating function for the number of partitions of n into an even number of distinct parts minus the number of partitions of n into an odd number of distinct parts. Each partition of n into an even … Zobraziť viac In mathematics, the pentagonal number theorem, originally due to Euler, relates the product and series representations of the Euler function. It states that In other words, Zobraziť viac The pentagonal number theorem occurs as a special case of the Jacobi triple product. Q-series generalize Euler's function, which is closely related … Zobraziť viac The identity implies a recurrence for calculating $${\displaystyle p(n)}$$, the number of partitions of n: Zobraziť viac We can rephrase the above proof, using partitions, which we denote as: $${\displaystyle n=\lambda _{1}+\lambda _{2}+\dotsb +\lambda _{\ell }}$$, where Zobraziť viac • Jordan Bell (2005).
