SphericalBesselY

SphericalBesselY[n, z]
gives the spherical Bessel function of the second kind y_n(z).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • SphericalBesselY[n, z] has a branch cut discontinuity in the complex z plane running from -∞ to 0.
  • Explicit symbolic forms for integer n can be obtained using FunctionExpand.
  • For certain special arguments, SphericalBesselY automatically evaluates to exact values.
