On Some Entire Modular Forms of an Integral Weight for the Congruence Subgroup Γ0(4𝑁)
Keyword(s):
Abstract Four types of entire modular forms of weight are constructed for the congruence subgroup Γ0(4𝑁) when 𝑠 is even. One can find these forms helpful in revealing the arithmetical meaning of additional terms in the formulas for the number of representations of positive integers by positive quadratic forms with integral coefficients in an even number of variables.
