complex variableIn mathematics, a variable that can take on the value of a complex number. In basic algebra, the variables x and y generally stand for values of real numbers. The algebra of complex numbers (complex analysis) uses the complex variable z to represent a number of the form a + bi. The modulus of z is its absolute value. A complex variable may be graphed as a vector from the origin to the point (a,b) in a rectangular coordinate system, its modulus corresponding to the vector's length. Called an Argand diagram, this representation establishes a connection between complex analysis and vector analysis. See also Euler's formula. complex variable [′käm‚pleks ′ver·ē·ə·bəl] (mathematics) A variable which assumes complex numbers for values. How to thank TFD for its existence?

Complex Analysis and Operator Theory" is devoted to the publication of current research developments in the related fields of complex analysis and operator theory as well as in application to system theory, harmonic analysis, probability, statistics, learning theory, and other related fields. The assessment of health risks associated with neurotoxic chemicals such as OP pesticides is a complex analysis that includes substantial uncertainty. A thought-provoking book, offering passionately charged arguments that should not be ignored, although it is unfortunately not long enough to give each difficult subject an appropriately in-depth complex analysis. |
