5: 21.1 Special Notation
Uppercase boldface letters are g × g real or complex matrices. The main functions treated in this chapter are the Riemann theta functions θ ( 𝐳 | 𝛀 ) , and the Riemann theta functions with characteristics θ [ 𝜶 𝜷 ] ( 𝐳 | 𝛀 ) . The function Θ ( ϕ | 𝐁 ) = θ ( ϕ / ( 2 π i ) | 𝐁 / ( 2 π i ) ) is also commonly used; see, for example, Belokolos et al. (1994, §2.5), Dubrovin (1981), and Fay (1973, Chapter 1).
