Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Weierstrass sigma function (σ) | Statement: [Sigma, denotes, Weierstrass sigma function (σ)]

Target entity: Weierstrass sigma function (σ)
Context triple: [Sigma, denotes, Weierstrass sigma function (σ)]

• A. Weierstrass elliptic functions
  Weierstrass elliptic functions are a class of doubly periodic meromorphic functions that play a central role in the theory of elliptic curves and complex analysis.
• B. Dedekind eta function
  The Dedekind eta function is a fundamental modular form in complex analysis and number theory, central to the theory of modular functions, partition identities, and connections with elliptic curves and string theory.
• C. Riemann–Siegel theta function
  The Riemann–Siegel theta function is a special function that appears in the study of the Riemann zeta function, used to express its values on the critical line in a form suitable for high-precision numerical computation.
• D. Mittag-Leffler function
  The Mittag-Leffler function is a complex function that generalizes the exponential function and plays a central role in fractional calculus and the theory of differential and integral equations.
