Casson Invariant and Gauge Theory
No full textIn this chapter, we give an account of SU(2)-gauge theory in dimension three. We discuss C. Taubes’ gauge-theoretical definition of the Casson invariant as (roughly) the Euler number of the gradient field of the Chern-Simons function. The Chern-Simons function plays a central role in modern understanding of homology 3-spheres, so we discuss it in some detail. An infinite dimensional analogue of Morse theory applied to the Chern-Simons function produces the instanton Floer homology which will be discussed in the next chapter. This gauge-theoretical approach to the Casson invariant leads to several extensions in a direction different from that of Walker and Lescop. One of the extensions we discuss is the SU(3) Casson invariant of H. Boden and C. Herald. Another one is the Casson-type invariant for knots in integral homology spheres introduced by X.-S. Lin and C. Herald, and finally, the equivariant Casson invariant of integral homology spheres with a finite cyclic group action by O. Collin and the author

The impact of double-diffusive convection on electroosmotic peristaltic transport of magnetized Casson nanofluid in a porous asymmetric channel
Full text linkThe primary objective of the present article is to investigate the heat and mass transfer in double diffusive mixed convection peristaltic flow of Casson nanofluid with solute diffusion through an asymmetric permeable channel filled with a porous medium in the presence of electroosmosis. Magnetohydrodynamics and radiative heat transfer are also considered. The study is motivated by industrial micro-pumping systems utilizing multi-functional nanomaterials. Researchers have investigated the distinct temperature and rheological properties of Casson nanofluids. Mixing nanoparticles with Casson fluid alters its flow characteristics and heat transmission, amalgamating different properties which are useful in a wide range of industrial and scientific applications. Buongiorno's two-component nanoscale model is deployed for simulating nanofluid transport, and the Rosseland diffusion flux is utilized for optically thick electromagnetic liquids. Heat generation or absorption and cross-diffusion (Soret and Dufour) effects are also incorporated in the model. An efficient analytical approach known as the long wavelength-low Reynolds number lubrication approximation (LWL-LRN) is utilized to solve the non-dimensional boundary value problem. Validation of the solutions with previous studies is included. Graphs are presented using MATLAB 2022b to visualize the influence of key parameters including permeability, magnetic field, thermal radiation, Grashof number, Brownian motion, thermophoresis, electrical field and Prandtl number on transport characteristics (velocity, temperature, concentration) and trapping phenomena associated with peristaltic propulsion. As thermophoresis and Brownian parameters are intensified, there is a strong response in nanoparticles which induces axial acceleration, as observed at locations y = 0.15, where u = 0.191, and y = 0.33, where u is elevated to 0.14. An increase in radiation parameter (í µí±í µí±) results in a depletion in axial velocity magnitudes along the left half of the wall and also modifies velocity distribution in the right section of the microchannel. An increase in the thermal radiation parameter (Rn) and heat absorption (sink) (<0) is found to suppress temperatures. Increasing heat generation, thermal Grashof number (Gr) and solutal Grashof number (Gc) decelerate axial flow in the left half space but accelerate flow in the right half space of the micro-channel. Increasing radiation parameter and thermal Biot number boost temperatures when heat sink is present but reduce them when heat source (generation) is present. Increasing radiation parameter boosts nanoparticle volume fraction (concentration) whereas an elevation in heat generation and thermal Biot number both induce the opposite effect. Increasing magnetic field damps the flow and reduces the number of boluses present. However, bolus volume increases with greater thermal Grashof Number(í µí°ºí µí±), Darcy (permeability) number (í µí°·í µí±) and Helmholtz-Smoluchowski velocity (í µí±ℎí µí±) i.e. stronger axial electrical field
Mixed convection casson fluid flow over an exponentially stretching sheet with Newtonian heating effect
Full text linkThis paper deals with mixed convection of Casson fluid which flows over a
heated surface that has been stretched exponentially. The governing equations that
govern the fluid flow are reduced to ordinary differential equations by imposing
suitable similarity variables. Numerical computational was carried out to solve for
the f “(0) and θ (0) for some arbitrary values of the mixed convection parameter λ,
Biot number Bi and Newtonian fluid parameter β when Pr =7
On the sheaf-theoretic SL(2, C) Casson–Lin invariant
No full textWe prove that the (τ-weighted, sheaf-theoretic) SL(2, C) Casson–Lin invariant introduced by Manolescu and the first author is generically independent of the parameter τ and additive under connected sums of knots in integral homology 3-spheres. This addresses two questions asked by Manolescu and the first author. Our arguments involve a mix of topology and algebraic geometry, and rely crucially on the fact that the SL(2, C) Casson–Lin invariant admits an alternative interpretation via the theory of Behrend functions.</p
