The structure, as seen in the mathematical and in the visual discourse within interdisciplinary projects and etudes, is the relatively intense topic for theoretical and practical research and application and for link between theory and practice and vice versa. Apart from the definition of the structural systems and the comparative method of historical and contemporary works of art, we find interesting to think about not only these, in the contribution opened areas, but also think about other new impulses to the problem of structure (both from artistic and mathematical point of view).
