'''法捷耶娃函数'''(Fadeeva function)是一种在等离子物理学中见到的特殊函数，与[[福格特函数]]有关，定义如下<ref>V. N. Faddeeva and N. N. Terent'ev: Tables of values of the function w(z)=\exp(-z^2)(1+2i/\sqrt{\pi}\int_0^z\exp(t^2)\text{d}t) for complex argument. Gosud. Izdat. Teh.-Teor. Lit., Moscow, 1954; English transl., Pergamon Press, New York, 1961. Unverified citation, copied from Poppe and Wijers (1990)</ref>

:<math>w(z):=e^{-z^2}\operatorname{erfc}(-iz) = \operatorname{erfcx}(-iz)
  =e^{-z^2}\left(1+\frac{2i}{\sqrt{\pi}}\int_0^z e^{t^2}\text{d}t\right).</math>


==与福格特函数的关系==

:<math>w(x+iy)=U(x,y)+iV(x,y)</math>,
