چکیده

Abstract In this article, we study a generalized Bohr radius $R_{p, q}(X), p, q\in [1, \infty )$ defined for complex Banach space X . particular, determine the exact value of q}(\mathbb {C})$ cases (i) $p, 2]$ , (ii) $p\in (2, ), and (iii) [2, Moreover, consider an n -variable version q}^n(X)$ quantity q}(X)$ q}^n(\mathcal {H})$ infinite-dimensional Hilbert $\mathcal {H}$ precise asymptotic as $n\to $ finite-dimensional We also multidimensional analog related concept called p -Bohr radius. To be specific, obtain -dimensional bounded complex-valued functions, in vector-valued case, provide lower estimate same, which is independent

Dispersive estimates for Schrödinger operators in dimensions one and three

A “resonance” here is defined to take place iff W (0) = 0 where W (λ) is the Wronskian of the two Jost solutions at energy λ2, see the following section. It is known that the spectrum of H is purely absolutely continuous on (0,∞) under our assumptions (V ∈ L1(R) suffices for that) so that Pac is the same as the projection onto the orthogonal complement of the bound states. For the case of three...

Monotonic subsequences in dimensions higher than one

The 1935 result of Erdős and Szekeres that any sequence of ≥ n +1 real numbers contains a monotonic subsequence of ≥ n+ 1 terms has stimulated extensive further research, including a paper of J. B. Kruskal that defined an extension of monotonicity for higher dimensions. This paper provides a proof of a weakened form of Kruskal’s conjecture for 2-dimensional Euclidean space by showing that there...

Efficient Approximation Algorithms for Point-set Diameter in Higher Dimensions

We study the problem of computing the diameter of a  set of $n$ points in $d$-dimensional Euclidean space for a fixed dimension $d$, and propose a new $(1+varepsilon)$-approximation algorithm with $O(n+ 1/varepsilon^{d-1})$ time and $O(n)$ space, where $0 < varepsilonleqslant 1$. We also show that the proposed algorithm can be modified to a $(1+O(varepsilon))$-approximation algorithm with $O(n+...

Generalized Duality and Singular Strings in Higher Dimensions

Deformations of gauged WZW actions are constructed for any pair (G, H) by taking different embeddings of the gauge group H ⊂ G as it acts on the left and right of the group element g. This leads to models that are dual to each other, generalizing the axial/vector duality of the two dimensional black hole manifold. The classical equations are completely solved for any pair (G, H) and in particul...

Zero Biasing in One and Higher Dimensions, and Applications

Given any mean zero, finite variance σ2 random variable W , there exists a unique distribution on a variable W ∗ such that EWf(W ) = σ2Ef ′(W ∗) for all absolutely continuous functions f for which these expectations exist. This distributional ‘zero bias’ transformation of W to W ∗, of which the normal is the unique fixed point, was introduced in [9] to obtain bounds in normal approximations. Af...
