sigma function मीनिंग इन हिंदी

Nonetheless his research continued; his seminal work on hyperelliptic sigma functions dates from around this period, being published in 1886 and 1888.
Another example is provided by the Weierstrass sigma function, which is quasiperiodic in two independent quasiperiods, the periods of the corresponding Weierstrass " & weierp; " function.
In entire function, it says " According to J . E . Littlewood, the Weierstrass sigma function is a'typical'entire function " Can anyone provide a formal citable reference for this?
I need to have f ( x, y ) \ geq sig _ 1 ( x ), and the idea is that f should combine these two sigma functions in a reasonable way that also has an " interaction " parameter.
The Weierstrass theory also includes the Weierstrass zeta function, which is an indefinite integral of & # 8472; and not doubly periodic, and a theta function called the Weierstrass sigma function, of which his zeta-function is the log-derivative.
