A fixed-point characterization of the inside-out (IO) and outside-in (OI) context-free tree languages is given. This characterization is used to obtain a theory of nondeterministic systems of context-free equations with parameters. Several “Mezei-a

Two-body Schrodinger Hamiltonians of the form H = H/sub 0/ + Q on L/sup 2/(R/sup 3/), where H/sub 0/ is the free Hamiltonian and Q the interaction, are considered. The main result is the fact, proved as a theorem, that the poles of S(E) and the reson

Based on graph separator theorems, we develop a new simulation technique which allows us to resolve several open problems for on-line computations: (1)One tape can nondeterministically simulate two nondeterministic pushdown stores in 0( n 1.5 √log

We examine a notion of duality which appears to be useful in situations where the usual convex duality theory is not appropriate because the functional to be minimized is not convex. The principle is a generalization of a duality theorem derived prev

Let M denote a smooth (Cm) n-dimensional manifold and let $: M x R -+ M denote a Cr flow (or dynamical system) which is generated by a CT vector field 4 (= (d/dt) +(t, x) j t = 0) on M (0 max(1, r}. In this case, we can only obtain Ck smoothness for

Following Sophus Lie, to a system of partial differential equations L(u) = 0 for unknown functions u = (ur ,..., un), of independent variables x = (x1 ,..., xn), we associate a locall group of transformations as follows. Roughly speaking a solution u

The classical inverse additive and multiplicative inverse eigenvalue problems for matrices are studied. Using general results on the solvability of polynomial systems it is shown that in the complex case these problems are always solvable by a finite

The Sobolev imbedding theorem and certain interpolation inequalities for Sobolev spaces are established for a wider class of domains than has been covered by earlier proofs. This class is defined by a weakened, measure theoretic version of the cone c
