TL;DR

This paper applies a novel 'Jacobi identity' in vertex operator algebras to generalize S. Bloch's work connecting values of the Riemann zeta function at negative integers to a Lie algebra of differential operators. By leveraging the algebraic structure of vertex operator algebras, the author derives new identities that unify zeta values with operator-theoretic constructions, extending previous results in number theory and mathematical physics.

ABSTRACT

We explain how to use a certain new "Jacobi identity" for vertex operator algebras, announced in a previous paper (math.QA/9909178), to interpret and generalize recent work of S. Bloch's relating values of the Riemann zeta function at negative integers with a certain Lie algebra of operators.

Motivation & Objective

• To interpret and generalize S. Bloch's recent results linking Riemann zeta values at negative integers to a Lie algebra of differential operators.
• To establish a deeper algebraic framework using vertex operator algebras to unify number-theoretic and operator-theoretic structures.
• To demonstrate how a newly formulated 'Jacobi identity' in vertex operator algebras can serve as a unifying principle across different mathematical domains.
• To extend the applicability of vertex operator algebra techniques to problems in zeta function theory and differential operator algebras.
• To provide a conceptual and computational bridge between quantum algebra, number theory, and theoretical physics via algebraic identities.

Proposed method

• Utilizes a recently announced 'Jacobi identity' for vertex operator algebras as the central algebraic tool.
• Applies the identity to derive operator relations involving differential operators acting on formal power series.
• Establishes connections between the structure of vertex operator algebras and the values of the Riemann zeta function at negative integers.
• Employs representation theory and Lie algebra techniques to interpret the resulting operator identities.
• Uses formal calculus and vertex algebra axioms to derive identities that generalize Bloch's original construction.
• Introduces a systematic method to generate zeta value identities through the algebraic properties of vertex operator algebras.

Experimental results

Research questions

• RQ1 How can the 'Jacobi identity' in vertex operator algebras be used to interpret and generalize Bloch's relation between zeta values and differential operators?
• RQ2 What algebraic structures underlie the connection between zeta values at negative integers and Lie algebras of differential operators?
• RQ3 In what way does the vertex operator algebra framework unify number-theoretic values with operator-theoretic constructions?
• RQ4 Can the new Jacobi identity be systematically applied to derive identities involving zeta functions and differential operators?
• RQ5 What is the role of vertex operator algebra symmetry in encoding arithmetic data such as zeta values?

Key findings

• The paper successfully generalizes Bloch's result by showing that zeta values at negative integers emerge naturally from the structure of a vertex operator algebra via the new Jacobi identity.
• The 'Jacobi identity' provides a unifying mechanism that links the algebraic properties of vertex operator algebras with arithmetic invariants like zeta values.
• The method constructs a Lie algebra of differential operators whose structure constants encode values of the Riemann zeta function at negative integers.
• The framework allows for the derivation of new identities involving zeta values and differential operators through purely algebraic means.
• The results establish a conceptual bridge between quantum algebra, number theory, and mathematical physics via vertex operator algebra techniques.
• The work demonstrates that the vertex operator algebra formalism can be used to systematically generate and interpret identities involving special values of zeta functions.
