In the case of one
complex variable, the set S([B.sup.1]) is denoted by S and LS([B.sup.1]) is denoted by LS.
where s is the
complex variable and the coefficients [k.sub.A1], [k.sub.A2], [k.sub.A3], [k.sub.B1], [k.sub.B2], [k.sub.B3] are determined based on the desired shape of the frequency characteristics (cut-off frequency, passband gain, pass-band ripple, stop-band slope, etc.).
We may find in the literature a large variety of convergent or asymptotic expansions of the special functions of mathematical physics that have the important property of being given in terms of elementary functions: direct or inverse powers of a certain
complex variable z and, sometimes, other elementary functions of z.
The numerical solution of two-dimensional Laplace equation with Dirichlet boundary conditions in doubly connected domain has been introduced by many authors; for example, the
complex variable boundary element methods has been presented in [5].
Let x be a
complex variable with [absolute value of x] < 1.
The theory of several
complex variables derives from the theory of one
complex variable.
The subject of basic sets of polynomials in one
complex variable, in its classical form, was introduced by Whittaker [1, 2] who laid down the definition of basic sets, basic series, and effectiveness of basic sets.
where [psi](j[omega]) is the function which all poles by
complex variable j[omega] are negative; [psi](-j[omega]) is the function which all poles by
complex variable j[omega] are positive.
With this, now our TIJ can finally help to address the need to mark
complex variable data directly on food packaging.
This technique is based on joint use of boundary integral equations method and the apparatus of the
complex variable theory.
