THE WEAK-TYPE (1, 1) OF FOURIER INTEGRAL OPERATORS OF ORDER −(n − 1)/2

چکیده
Let T be a Fourier integral operator on R n of order −(n − 1)/2. In [4] it was shown (among other things) that T maps the Hardy space H 1 to L 1. In this note we show that T is also of weak-type (1, 1). The main ideas are a decomposition of T into non-degenerate and degenerate components, and a factorization of the non-degenerate portion.

THE WEAK - TYPE ( 1 , 1 ) OF FOURIER INTEGRAL OPERATORS OF ORDER - ( n - l ) / 2
Let T be a Fourier integral operator on K" of order —(n — l)/2. Seeger, Sogge, and Stein showed (among other things) that T maps the Hardy space H to L. In this note we show that T is also of weak-type (1, 1). The main ideas are a decomposition of T into non-degenerate and degenerate components, and a factorization of the non-degenerate portion. 2000 Mathematics subject classification: primary ...
متن کاملOn the Integral Representations of Generalized Relative Type and Generalized Relative Weak Type of Entire Functions
In this paper we wish to establish the integral representations of generalized relative type and generalized relative weak type as introduced by Datta et al [9]. We also investigate their equivalence relation under some certain conditions.
متن کاملBoundedness of Fourier Integral Operators on Fourier Lebesgue Spaces and Affine Fibrations
We carry on the study of Fourier integral operators of Hörmander’s type acting on the spaces FL(R)comp, 1 ≤ p ≤ ∞, of compactly supported distributions whose Fourier transform is in L. We show that the sharp loss of derivatives for such an operator to be bounded on these spaces is related to the rank r of the Hessian of the phase Φ(x, η) with respect to the space variables x. Indeed, we show th...
متن کاملÜ Bounds for Spectral Multipliers on Nilpotent Groups
A criterion is given for the Lp boundedness of a class of spectral multiplier operators associated to left-invariant, homogeneous subelliptic second-order differential operators on nilpotent Lie groups, generalizing a theorem of Hörmander for radial Fourier multipliers on Euclidean space. The order of differentiability required is half the homogeneous dimension of the group, improving previous ...
متن کاملOn $F$-Weak Contraction of Generalized Multivalued Integral Type Mappings with $alpha $-admissible
The purpose of this work is to investigate the existence of fixed points of some mappings in fixed point theory by combining some important concepts which are F-weak contractions, multivalued mappings, integral transformations and α-admissible mappings. In fixed point theory, it is important to find fixed points of some classess under F- or F-weak contractions. Also multivalued mappings is the ...
