<正> Let f*g (z) be the convolution or Hadamard product of two functiom f(z) and g(z), that is, if f (z) =z+sum from n=2 to ∞a_nz~n and g(z) =z+sum from n=2 to
<正> Let B be a Banach space, {T_(s,t), 0≤s≤t≤∞} be a two-parameter contraction semigroup on B, and {R_(λ,s),λ>0, s≥0} be the right resolvent. Definition
<正> In this paper, a new method is developed to solve the N-S equations with vorticity-velocity variables, which is suitable for describing the flow-field of t
