In the article we prove the Casson Invariant Conjecture of Neumann– Wahl for splice type surface singularities. Namely, for such an isolated complete intersection, whose link is an integral homology sphere, we show that the Casson invariant of the link is one-eighth the signature of the Milnor fiber.

We show that the SU(3) Casson invariant for spliced sums along certain torus knots equals 16 times the product of their SU(2) Casson knot invariants. The key step is a splitting formula for su(n) spectral flow for closed 3-manifolds split along a torus.

Unsteady flow of Casson fluid past through a vertical channel has been studied by some researchers due to its importance applications in science and technology. Therefore, the main purpose this paper is obtain exact solutions for unsteady free convection flows with effects magnetohydrodynamics (MHD) channel. This continued study from published article [18] additional (MHD). Dimensional governing...

Numerical results are presented for the effect of first order chemical reaction and thermal radiation on mixed convection flow of Casson fluid in the presence of magnetic field. The flow is generated due to unsteady nonlinearly stretching sheet placed inside a porous medium. Convective conditions on wall temperature and wall concentration are also employed in the investigation. The governing pa...

A numerical evaluation of the crucial physical properties a 3D unsteady MHD flow along stretching sheet for Casson fluid in presence radiation and viscous dissipation has been carried out. Meanwhile, by applying similarity transformations, nonlinear partial differential equations (PDEs) are transformed into system ordinary (ODEs). Furthermore, solution ODEs, shooting method with Adams Moulton o...
