Finally, we present Jacobi’s elliptic functions ., and ., and we derive the nonlinear ordinary differential equations that they satisfy. These functions are also very us舞蹈编排 发表于 2025-3-24 21:26:00

When .>2, we have a new class of multivariable hypergeometric functions. Finally, we use matrix differential operators and Fourier expansions to solve the MaOffstage 发表于 2025-3-25 01:59:14
