    Oscillatory and Fourier Integral operators with degenerate canonical relations

    Get PDF
    We mostly survey results concerning the L2L^2 boundedness of oscillatory and Fourier integral operators. This article does not intend to give a broad overview; it mainly focusses on a few topics directly related to the work of the authors.Comment: 37 pages, to appear in Publicacions Mathematiques (special issue, Proceedings of the 2000 El Escorial Conference in Harmonic Analysis and Partial Differential Equations

    A note on restricted X-ray transforms

    Full text link
    We show how the techniques introduces by Christ can be employed to derive endpoint Lpāˆ’LqL^p-L^q bounds for the X-ray transform associated to the line complex generated by the curve tā†’(t,t2,...,tdāˆ’1).t\to(t,t^2,...,t^{d-1}). Almost-sharp Lorentz space estimates are produced as well.Comment: 11 page

    Electromagnetic wormholes via handlebody constructions

    Full text link
    Cloaking devices are prescriptions of electrostatic, optical or electromagnetic parameter fields (conductivity Ļƒ(x)\sigma(x), index of refraction n(x)n(x), or electric permittivity Ļµ(x)\epsilon(x) and magnetic permeability Ī¼(x)\mu(x)) which are piecewise smooth on R3\mathbb R^3 and singular on a hypersurface Ī£\Sigma, and such that objects in the region enclosed by Ī£\Sigma are not detectable to external observation by waves. Here, we give related constructions of invisible tunnels, which allow electromagnetic waves to pass between possibly distant points, but with only the ends of the tunnels visible to electromagnetic imaging. Effectively, these change the topology of space with respect to solutions of Maxwell's equations, corresponding to attaching a handlebody to R3\mathbb R^3. The resulting devices thus function as electromagnetic wormholes.Comment: 25 pages, 6 figures (some color

    Domestic Drone Surveillance: The Courtā€™s Epistemic Challenge and Wittgensteinā€™s Actional Certainty

    Get PDF
    This article examines the domestic use of drones by law enforcement to gather information. Although the use of drones for surveillance will undoubtedly provide law enforcement agencies with new means of gathering intelligence, these unmanned aircrafts bring with them a host of legal and epistemic complications. Part I considers the Fourth Amendment and the different legal standards of proof that might apply to law enforcement drone use. Part II explores philosopher Wittgensteinā€™s notion of actional certainty as a means to interpret citizens' expectations of privacy with regard to their patterns of movement over time. Part III discusses how the theory of actional certainty can apply to the epistemic challenge of determining what is a ā€œreasonableā€ expectation of privacy under the law. This Part also investigates the Mosaic Theory as a possible reading of the Fourth Amendment
