چکیده

By using the symmetry of Dunkl Laplacian operator, we prove a sharp Shannon-type inequality and logarithmic Sobolev for transform. Combining these inequalities, obtain new, short proof Heisenberg-type uncertainty principles in setting. Moreover, by combining Nash’s inequality, Carlson’s Sobolev’s embedding theorems transform, new inequalities involving L∞-norm. Finally, Lp-spaces, from which derive an Lp-Heisenberg-type Lp-Nash-type

Extremal Sobolev Inequalities and Applications

Proof Let f : R → R be any smooth function that is identically 1 for t ≤ 0 and identically 0 for t ≥ 1. Since H k(R) is the completion of C∞(Rn), it is enough to show that every function φ ∈ C∞(Rn) ∩ H k(R) can be approximated in H k(R n) by functions in C∞ c (Rn). Consider the sequence φj(x) := φ(x)f(|x| − j). We have that φj ∈ C∞ c (Rn): in fact |x| is not differentiable at x = 0, but f(t) is...

Noncommutative Extensions of the Fourier Transform and Its Logarithm

We introduce noncommutative extensions of the Fourier transform of probability measures and its logarithm in the algebra A(S) of complex-valued functions on the free semigroup on two generators S = FS({z,w}). First, to given probability measures μ, ν whose all moments are finite, we associate states μ̂, ν̂ on the unital free *-bialgebra (B, ǫ,∆) on two self-adjoint generators X,X ′ and a projecti...

Pseudo-Poincaré Inequalities and Applications to Sobolev Inequalities

Most smoothing procedures are via averaging. Pseudo-Poincaré inequalities give a basic L-norm control of such smoothing procedures in terms of the gradient of the function involved. When available, pseudo-Poincaré inequalities are an efficient way to prove Sobolev type inequalities. We review this technique and its applications in various geometric setups.

Research Article Logarithm of the Discrete Fourier Transform

Our choice of normalization factor ensures that F is unitary: F† ◦F = I , where I is the identity transformation, and F† is the Hermitian conjugate of F, that is, (F†) jk = Fk j . Also recall that the exponential of a matrix M is given by the infinite series (M) . = ∑∞ p=0(1/p!)M (provided it converges). Thus a complex-linear map f : Cn→Cn is a logarithm for F if F = exp ( f ), and we write f =...
