Contact geometry treats such questions as the existence and classification of contact structures on manifolds of odd dimension and specified topological structure. See inequality (1) below. The geometric/analytic approach treated in this report introduces parabolic systems of partial differential equations (PDEs) in a way which complements the betterknown, more algebraic methods. This is a repo...

this paper presents a numerical simulation of developing flow and heat transfer of a viscoelastic fluid in a rectangular duct. in fully developed flow of a viscoelastic fluid in a non-circular duct, secondary flows normal to the flow direction are expected to enhance the rate of heat and mass transfer. on the other hand, properties such as viscosity, thermal conductivity, specific heat and rela...
