11. Their website further explores the mathematical structure of the picture. 12. For every natural mathematical structure there is a & sigma;-structure. 13. It shows that spaces are just mathematical structures of convenience. 14. The electromagnetic field tensor displays the manifestly covariant mathematical structure of the electromagnetic field. 15. Category theory is a branch of mathematics that formalizes mathematical structure and its concepts. 16. The most suitable mathematical structure seemed to be a tensor. 17. The intricate mathematical structure of this spectrum was discovered by Soviet physicist Mark Ya. 18. Model theory analyzes formulae with respect to particular classes of interpretation in suitable mathematical structures . 19. Fascination with quaternions began before the language of set theory and mathematical structures was available. 20. Many mathematical structures are defined through a characterizing property ( often a universal property ).
