*The basic theta function is defined to be the function <math>\theta : \mathbb{C} → \mathbb{C} </math> given by     

*The basic theta function is defined to be the function <math>\theta </math>:<math> \mathbb{C} → \mathbb{C} </math> given by     

*The function <math>\theta</math> depends on <math>\tau</math>τ .  

*The function <math>\theta</math> depends on <math>\tau</math>τ .  

*So for each <math>\tau \in \mathbb{C}</math>τ ∈ C with Im τ > 0 we get a (not necessarily different) basic theta function.
