A Hilbert module over a planar algebra is essentially a Hilbert module over a eanonieally defined algebra spanned by the annular tangles in It follows that any planar algebra containing is a module over and in particular, any subfactor planar algebra is a module over the Temperley-Lieb planar...

The nonlinear eigenvalue problem Δ+λ = 0 in the unit square with = 0 on the boundary is often referred to as “the Bratu problem” or “Bratu's problem.” The Bratu problem in 1-dimensional planar coordinates, ″ + λ = 0 with (0) = (1) = 0 has two known, bifurcated, exact solutions for...

We make a study of quasi-Hopf algebras and quasi-Hopf subalgebras over certain commutative rings from the point of view of Frobenius algebras. Separability and strong separability of quasi-Hopf algebras are also studied from this point of view

We present some formal systems in the language of linearly ordered rings with finite sets whose nonlogical axioms are strictly mathematical, which correspond to polynomially bounded arithmetic. With an additional strictly mathematical axiom, the systems correspond to exponentially bounded arithmetic

Let be a proper cone in , let be an × real matrix that satisfies , let be a given vector of , and let λ be a given positive real number. The following two linear equations are considered in this paper: (i) (λ — ) = , ∈ , and (ii) ( — λ) = , ∈ . We obtain several equivalent conditions...

The visco-elastic fluids in computational fluid mechanics (CFM) is an important problem to study. The simulation of the process of shear and elongation material has been successfully carried out in our previous reports (reference [1]). A mixed computational and mathematical approach in...

Two general procedures for computing eigenvalues and error estimates in Sturm-Liouville problems based upon the shooting technique are considered. The proposed methods have a low computational cost and the error estimates can be employed to improve the approximations obtained for the...

Should the generosity of unemployment benefits and the progressivity of income taxes depend on the presence of business cycles? This paper proposes a tractable model where there is a role for social insurance against uninsurable shocks to income and unemployment, as well as inefficient business...
