Improved bounds on negativity of superpositions
We consider an alternative formula for the negativity based on a simple generalization of the concurrence. We use the formula to bound the amount of entanglement in a superposition of two bipartite pure states of arbitrary dimension. Various examples indicate that our bounds are tighter than the previously known results.
متن کاملUniversal approximation bounds for superpositions of a sigmoidal function
Approximation properties of a class of artificial neural networks are established. It is shown that feedforward networks with one layer of sigmoidal nonlinearities achieve inte grated squared error of order O(l/n), where n is the number of nodes. The function appruximated is assumed to have a bound on the first moment of the magnitude distribution of the Fourier transform. The nonlinear parame...
متن کاملImproved bounds on the conductivity
Diierent bounds on the conductivity of a composite material may improve on each other in diierent conductivity regimes. If so, the question arises of how to eeciently interpolate between the bounds. In this paper we show how to do an interpolation with a two-point Pad e approximation method. For bounds on two-component composites the interpolation method is shown to be, in a sense, the best pos...
متن کاملImproved Bounds on the Weak
We show that the known bounded-depth proofs of the Weak Pigeonhole Principle PHP 2n n in size n O(log(n)) are not optimal in terms of size. More precisely, we give a size-depth trade-oo upper bound: there are proofs of size n O(d(log(n)) 2=d) and depth O(d). This solves an open problem of Maciel, Pitassi and Woods (2000). Our technique requires formalizing the ideas underlying Nepomnja s cij's ...
متن کاملImproved Bounds on the Supremum of Autoconvolutions
We give a slight improvement of the best known lower bound for the supremum of autoconvolutions of nonnegative functions supported in a compact interval with a fixed integral. Also, by means of explicit examples we disprove a long standing natural conjecture of Schinzel and Schmidt concerning the extremal function for such autoconvolutions. 2000 Mathematics Subject Classification.
