We have investigated the solvation shell dynamics of Na and Cl ion pairs in water DMSO mixtures of three compositions with xDMSO (mole fraction of DMSO) = 0.21, 0.35 and 0.48. Dynamical ion pair trajectories in these compositions are studied to analyze the diffusional behaviour of the solvent molecules in the primary and secondary solvation shells as well as the bulk solvent. As expected, the d...

The role of mathematics in economic analysis is not yet a settled question. Smith, Ricardo, Mill and other eminent classical economists did not use mathematics in their economic theorizations. We have defined classical mathematical economics as the whole body of literature in mathematical treatment of economics originating mainly from the contributions of Cournot,  Jevons and Walras.
