SOME RECENT DEVELOPMENTS IN FOURIER ANALYSIS AND iP-THEORY ON PRODUCT DOMAINS BY SUN-YUNG A. CHANG AND ROBERT FEFFERMAN

Introduction. In this article we wish to discuss a theory which is still developing very rapidly. It is only quite recently that many of the aspects of Fourier analysis of several parameters have been discovered, even though much of the corresponding one-parameter theory has been well known for some time. The topics to be covered include differentiation theory, singular integrals, Littlewood-Pa...

FOURTH ORDER EQUATIONS IN CONFORMAL GEOMETRY by Sun - Yung

— In this article we review some recent work on fourth order equations in conformal geometry of three and four dimensions. We discuss an existence result for a Yamabe-type equation in dimension three. We examine a generalization of the Cohn-Vossen inequality to dimension four. Finally, we review an application of the fourth order equation to a fully nonlinear equation in dimension four that inv...

On the prescribing σ 2 curvature equation on S 4 Sun - Yung

Prescribing σk curvature equations are fully nonlinear generalizations of the prescribing Gaussian or scalar curvature equations. For a given a positive function K to be prescribed on the 4-dimensional round sphere, we obtain asymptotic profile analysis for potentially blowing up solutions to the σ2 curvature equation with the given K; and rule out the possibility of blowing up solutions when K...

dytogenetic analysis of hela and chang cells

based on the evaluation of two human cell lines, hela and chang, abeuploidy and several marker chromosomes were found in both cells. the morphological characteristic of marker chromosomes of chang cells was distinctly different from hela. certain submetacentric marker chromosome was frequently present among 80% of marker chromosomes of chang cells which distinguished this line from hela, which ...
