    Notes: Summary. The functions $f_1(x), \dots, f_r(x)$ are refinable if they are combinations of the rescaled and translated functions $f_i(2x-k)$ . This is very common in scientific computing on a regular mesh. The space $V_0$ of approximating functions with meshwidth $h=1$ is a subspace of $V_1$ with meshwidth $h=1/2$ . These refinable spaces have refinable basis functions. The accuracy of the computations depends on $p$ , the order of approximation, which is determined by the degree of polynomials $1, x, \dots, x^{p-1}$ that lie in $V_0$ . Most refinable functions (such as scaling functions in the theory of wavelets) have no simple formulas. The functions $f_i(x)$ are known only through the coefficients $c_k$ in the refinement equation – scalars in the traditional case, $r \times r$ matrices for multiwavelets. The scalar "sum rules" that determine $p$ are well known. We find the conditions on the matrices $c_k$ that yield approximation of order $p$ from $V_0$ . These are equivalent to the Strang–Fix conditions on the Fourier transforms $\hat f_i(\omega)$ , but for refinable functions they can be explicitly verified from the $c_k$ .

    Notes: Abstract We study the space BD(Ω), composed of vector functions u for which all components εij=1/2(u i, j+u j, i) of the deformation tensor are bounded measures. This seems to be the correct space for the displacement field in the problems of perfect plasticity. We prove that the boundary values of every such u are integrable; indeed their trace is in L 1 (Γ)N. We show also that if a distribution u yields ɛ ij which are measures, then u must lie in L p(Ω) for p≦N/(N−1).

    Notes: Summary The rate of convergence of the finite element method depends on the order to which the solutionu can be approximated by the trial space of piecewise polynomials. We attempt to unify the many published estimates, by proving that if the trial space is complete through polynomials of degreek−1, then it contains a functionv h such that |u−v h | s ≦ch k−s|u| k . The derivatives of orders andk are measured either in the maximum norm or in the mean-square norm, and the estimate can be made local: the error in a given element depends on the diameterh i of that element. The proof applies to domains Ω in any number of dimensions, and employs a uniformity assumption which avoids degenerate element shapes.

    Notes: Abstract Dual extremum principles are established in this paper for the variational boundary-value problem of elasto-perfect plasticity with large deformation. There exists a duality gap between the primal and dual variational problems. Our application to nonlinear limit analysis yields a pair of dual bounding theorems for the safety factor, when the gap has the right sign. It is proved that both the upper and lower bounds directly depend on the properties of the dual gap function.
