On first integrals of linear systems, Frobenius integrability theorem and linear representations off Frobenius integrability theorem. This condition is also generically sufficient for the local existence of such a common first integral. We study here the question of the existence of a global common first integral for compatible linear vector fields in ℝ...For the dimension 3, we prove that any tw

Epigenetics in Crop Improvementer, we are interested in the characterization of porous media. Our attention is drawn to develop a method to describe accurately the pore network microstructure of porous materials as presented in[.]. This work proposes an efficient algorithm based on the distance transform method[.] which is a wide
