## a b s t r a c t A projective invariant generalization of the de Casteljau algorithm is described by using the cross ratio and an auxiliary line. We describe the implicit form of the section conics obtained by the algorithm proposed in this paper. Finally, we show how to construct specific conic

A b s t r a c t , A generalized Dirac equation is presented as a model theory of disturbed Lorentz invariance. The physical properties of this model and experimental consequences are discussed. A program its described how such Lorentz noninvariant equations may be produced by cosmologicel induction
## An improvement of the Peano-Baker iterative method (mat&ant method) for solving a system of first order linear differential equations with variable coe$cients is presented. The new method utilizes the structure of the matrix of coe$cients to de&e iterative schemes which may converge much more
