戣栚丗 The Fourier transform of a function of bounded variation

奣梫丗 New relations between the Fourier transform of a function of bounded variation and the Hilbert transform of its derivative are revealed. The main result is an asymptotic formula for the {\bf cosine} Fourier transform. Such relations have previously been known only for the sine Fourier transform. Interrelations of various function spaces are studied in this context, first of all of two types of Hardy spaces. The obtained results are used for proving completely new results on the integrability of trigonometric series. Multidimensional extensions are discussed as well.

戣栚丗 Slopes of colored links

奣梫丗 This work is motivated by our previous study of the behavior of the signature of colored links under the splice operation. The signature is mainly additive, with a regular correction term related to the generalized Hopf links. However, this almost additivity is lost along a certain ``singular locus,'' which is the subject of our current work. To describe the extra correction term (arising as a Maslov index in Wall's non-additivity theorem), we introduce a collection of invariants of colored links, called slopes. It turns out that the slope can be represented as the ratio of two sign-refined Alexander polynomials (or rather derivatives thereof), whenever this ratio makes sense. However, experiments with the link tables show that, when both polynomials in question vanish, the rational function obtained is independent of the higher Alexander polynomials, thus providing a new link invariant. (This invariant does distinguish some of the links in the tables.) Even isolated common zeroes of the two polynomials sometimes lead to surprises, as l'H\^opital's rule does not work.
Should time permit, I will discC43uss further properties of the new invariants and outline several ways of computing them.
This is a joint work in progress with Vincent Florens and Ana G. Lecuona.

奣梫丗We first obtain two classes of orthonormal bases for $L^2([0,1])$. The exponential parts of bases that are multi-knot piecewise linear functions are called spectral sequences. We also consider an inverse problem for single-knot piecewise linear spectral sequences. We characterize $L^p([0,1])$ spaces with $1 < p < \infty$ in using one class of orthonormal bases. In addition, we will give the corresponding Littlewood-Paley theorem, Carleson-Hunt theorem and Poisson summation formula related to these bases.

戣栚 : An introduction of composition operators on function spaces

奣梫丗Let $\varphi$ be an analytic self map of the unit disk in the complex plane. A composition operator induced by $\varphi$ is defined by $C_{\varphi}f=f\circ\varphi$ for $f$ in the space of functions analytic on the unit disk. The study of Composition operators has originated in 1960s. It is one of the fast growing areas in mathematics. In my talk I will introduce some basic facts on composition operators, and some of its recent developements.

奣梫丗we construct complete embedded minimal surfaces in $\Bbb H^2\times \Bbb R$. The first one is a finite total curvature surface which is conformal to $\mathbb S^2\setminus\{p_1,...,p_k\}, k\ geq2$. The complete embedded minimal surfaces, with $k$ vertical planar ends and total curvature $-4(k-1)\pi$, give an affirmative answer to Hauswirth and Rosenberg's question. The second one is a 2-parameter family of minimal surfaces which have finite total curvature and asymptotically converge to several vertical planes. These are similar to the Scherk's towers in $\Bbb R^3$. In the second case, we construct the minimal surfaces by the conjugate surface and barrier method.

(The first proof of contractibility of Teichmuller spaces is given by Douady-Earle barycentric extension.) Finally, we consider the maximum possible decay of earthquake measures in the unit disk.

Kaneko obtained two formulas for the values of poly-Bernoulli numbers. In this talk, we will investigate Kaneko's formulas from a combinatorial point of view. It will be shown that his formulas are essentially the same as the computation of the number of lonesum matrices in two ways, namely, using the principle of inclusion and exclusion in the first hand, and using the partition of a given set in the second hand. We also present our recent results on ternary lonesum matrices.

Abstract:We develop and study a Lefschetz theory in a combinatorial category associated to a root system and derive an upper bound on the exceptional characteristics for Lusztig's character formula for simple rational representations of a reductive algebraic group. Our bound is huge compared to the Coxeter number, it is, however, given by an explicit formula.
