Abstract

The convergence of the Galerkin approximations to solutions of abstract evolution equations of the form uβ€²(t)= βˆ’ Au(t) + M(u(t)) is shown. Here A is a closed, positive definite, self‐adjoint linear operator with domain D(A) dense in a Hilbert space H and M is a non‐linear map defined on D(A^Β½^) which satisfies a Lipschitz condition on balls in D(A^Β½^).

In this paper, we introduce "approximate solutions" to solve the following problem: given a polynomial F (x, y) over Q, where x represents an n-tuple of variables, can we find all the polynomials G(x) such that F (x, G(x)) is identically equal to a constant c in Q? We have the following: let F (x, y
