Abstract:In this article, the authors survey and review the recent studies of boundary value problems for regular functions in Clifford analysis, which include theoretical foundations and useful methods. These theoretical bases consist of the generalized Cauchy theorem and the generalized Cauchy integral formula, the Painlev'{e} type theorem and the boundary behaviors of the Cauchy type integrals, as well as various integral representations. Certain boundary value problems and singular integral equations in the Clifford algebra setting are introduced. | |||

Abstract:Let $f$ be a parabolic transcendental meromorphic function with positive and finite order $ ho$ and its derivative satisfies some growth conditions. In this paper, we show the existence of conformal measures and use this basic tool to illustrate both geometrical and dynamical features of the radial Julia set. We also characterize the conformal measures supported on radial Julia sets. | |||

Abstract:In 1960's Kra asked whether $tmu$ $(0<t<1)$ is a trivial Beltrami coefficient whenever $mu$ is trivial, and Gehring and Reich-Strebel independently gave some counter-examples to this question. In this short note we will discuss Kra's question in another direction, namely, we are concerned with those Beltrami coefficients $mu$ such that all $tmu$ $(0le tle 1)$ are trivial. An application is given to the geodesic segments in infinite dimensional Teichm"uller spaces. | |||

Abstract:Let $(X, d, mu)$ be a metric measure space, with $mu$ a Borel regular measure.In this paper, we prove that, if $uin L^1_loc(X)$ and $g$ is aHajl asz gradient of $u$, then there exists $widetilde u$ such that$widetilde u=u$almost everywhere and $4g$ is a $p$-weakupper gradient of $widetilde u$. This result avoids a priori assumptionon the quasi-continuity of $u$ used in [Rev. Mat. Iberoamericana 16 (2000), 243-279].As an application, an embedding of the Morrey-type function spaces based on Hajl asz-gradientsinto the corresponding function spaces based on upper gradients is obtained. We also introducethe notion of local Hajl asz gradient, and investigate the relations between local Hajl asz gradientand upper gradient. | |||

Abstract:It is proved that in any infinite dimensional Teichm"uller space, if there exist more than one geodesic segments between two points, then there must exist infinitely many geodesic segments joining them such that each pair of these geodesic segments are tangent to each other at both endpoints. This answers a question posed by Z. Li in 2012. | |||

Abstract:Optimal recovery means that using finitely manyarbitrary function values f(x) for some x∈D to reconstruct(recovery) functions f from a given classes with the least possible errors. Optimal recovery constitutes a important ingredient innumerical analysis and has many important practical applications.There are two most important case setting: worst case setting andaverage case setting as far as error measure is concerned. In thispaper, optimal recovery (reconstruction) of functions on the spherein the average case setting is studied. The asymptotic orders ofaverage sampling numbers of a Sobolev space on the sphere with aGaussian measure in the Lq(sd-1) metric for 1≤q≤∞ are obtained, and it is shown that some worst-caseasymptotically optimal algorithms are also asymptotically optimal in the average case setting inthe Lq(sd-1) metric for 1≤q≤∞. | |||
