New polynomial analogues of Jacobi's triple product and Lebesgue's identities [PDF]

open access: yesAdvances in Applied Mathematics, 2004
In a recent paper by the authors, a bounded version of Goellnitz's (big) partition theorem was established. Here we show among other things how this theorem leads to nontrivial new polynomial analogues of certain fundamental identities of Jacobi and Lebesgue. We also derive a two parameter extension of Jacobi's famous triple product identity.

A Vanishing Finite Sum associated with Jacobi's triple product identity [PDF]

open access: yesJournal of Combinatorial Theory, 1969
AbstractJacobi's triple product identity is shown to be equivalent to the vanishing of a finite sum. The vanishing of the sum is then established independently of Jacobi's identity, and the behavior of a related finite sum is discussed. Finally, the possibility of generalizing Jacobi's identity to include variables with non-quadratic exponents is ...

Jacobi's triple product identity and theta function identities [PDF]

open access: yesMathematical Communications, 2011
As a unified approach, Jacobi's triple product identity will be utilized to derive theta function formulae due to Baruah-Berndt (2007), identities of Rogers--Ramanujan functions and modular equations due to Ramanujan.

Euler's Pentagonal Number Theorem Implies the Jacobi Triple Product Identity

open access: yesIntegers, 2011
AbstractBy means of Liouville's theorem, we show that Euler's pentagonal number theorem implies the Jacobi triple product identity.

Jacobi's identity and the König-Egerváry theorem [PDF]

open access: yes, 1984
The König-Egerváry theorem, which asserts that the maximum size of a partial matching in a relation equals the minimum size of a separating set, is proved using Jacobi's identity relating complementary minors in a matrix and its ...

The multisection method for triple products and identities of Rogers–Ramanujan type [PDF]

open access: yes, 2008
By applying the bisection and trisection method to Jacobi's triple product identity, we establish several identities factorizing sum and difference of infinite products, which lead, in turn, to new and elementary proofs for twenty identities of Rogers ...

The Triple Helix of University-Industry-Government Relations [PDF]

open access: yes, 2012
Etzkowitz & Leydesdorff (2000) further elaborated the Triple Helix of University-Industry-Government Relations (cf. Etzkowitz & Leydesdorff, 1995; Lowe, 1982) into a model for studying knowledge-based economies.

The role of the user and the society in new product development [PDF]

open access: yes, 2010
Within the knowledge-based economy several institutions are involved in product innovation processes. Literature study has shown that the most researched and cited are the industry-universitygovernment relations, presented in the Triple Helix model of ...

A triple product identity for Schur functions [PDF]

open access: yes, 1991
In this paper we expand the product of n different classical theta functions into a Laurent sum of Schur symmetric functions of their arguments. This expansion is a natural extension of the Jacobi triple product identity.
