H.; Mirshafizadeh, M. The theory of mathematical analysis over split quaternions is formulated in a closest possible analogy to the usual theory of analytic functions of a complex variable. After reviewing split quaternion algebra via an isomorphic 4 £ 4 matrix representation, a different definition is given to partial derivatives involving split quaternions. This takes care of the ambiguity involved in the no commutative properties of split quaternions. A closely analogous condition for analyticity of functions of a split quaternion variable is found. The analogy with complex variables is illustrated for both the derivative. Mon, 17 Oct 2011 20:44:47 GMT http://www.saber.ula.ve/handle/123456789/33886 2011-10-17T20:44:47Z
