Strongly Singular Integrals on Stratified Groups
نویسندگان
چکیده
We consider a class of spectral multipliers on stratified Lie groups which generalise the Hormander and include with an oscillatory factor. Oscillating have been examined extensively in Euclidean setting where sharp, endpoint Lp estimates are well known. In group setting, corresponding bounds for oscillating established by several authors but only open range exponents. this paper we establish Lp(G) bound when G is group. More importantly begin to address whether these sharp.

Strongly singular integrals along curves on α-modulation spaces
In this paper, we study the strongly singular integrals [Formula: see text] along homogeneous curves [Formula: see text]. We prove that [Formula: see text] is bounded on the α-modulation spaces, including the inhomogeneous Besov spaces and the classical modulation spaces.
متن کاملOn Strongly $H_{v}$-groups
The largest class of hyperstructures is the one which satisfies the weak properties; these are called $H_{v}$-structures. In this paper we introduce a special product of elements in $H_{v}$-group $H$ and define a new class of $H_{v}$-groups called strongly $H_{v}$-groups. Then we show that in strongly $H_{v}$-groups $beta=beta^{ast}$. Also we express $theta$-hyperoperation and investigat...
متن کاملGauss-chebyshev Quadrature Formulae for Strongly Singular Integrals
This paper presents some explicit results concerning an extension of the mechanical quadrature technique, namely, the Gauss-Jacobi numerical integration scheme, to the class of integrals whose kernels exhibit second order of singularity (i.e., one degree more singular than Cauchy). In order to ascribe numerical values to these integrals they must be understood in Hadamard's finite-part sense. T...
متن کاملSingular Integrals on Hilbert Space
exists as a bounded operator on L(H) as ô tends to zero and p tends to infinity. A theorem of this type extends the Calderon-Zygmund theory of singular integral operators on En to infinite dimensions. For if fc(#)||x||-" is a Calderon-Zygmund kernel and if £ is a bounded Borel set which is disjoint from a neighborhood of the origin then v{E) =fEk(x)\\x\\~ dx satisfies v(tE) = v(E) for £>0; if g...
متن کاملSingular Integrals
In this paper I will a t tempt to describe the subject as it has developed in the last fifteen years, outlining the methods by which its problems have been approached and discussing its connections with other branches of Analysis. I t will perhaps be best to start by considering certain classical situations which lead naturally to singular integrals and which contain the seeds of some of the me...
