Superconvergence for L^2-projection.in finite elements

Chinese Science Bulletin 1998年第1期43卷 22-24页

作者： CHEN Chuanmiao Institute of Computing, Hunan Normal University, Changsha 410081, China Hunan Normal University Institute of Computing Changsha China

Two classes of superconvergence points for L 2 projection.u\-n in n degree finite elements on uniform grids are shown by element analysis method. Superconvergence points of u n are n+1 order Gauss point G n+1 for odd d≥1 (so the endpoint of each element is of superconvergent), and n+1 order pointset Z n+1 for even n ≥2 (which includes the endpoints and midpoint), respectively. Symmetry point is only an important part of them.

关键词： superconvergence finite elements L 2 projection.

Chinese Science Bulletin 1999年第8期44卷 688-690页

作者： ZHANG Lunchuan and MA JipuDepartment of Mathematics , Beijing Normal University , Beijing 100875, China Department of Mathematics , Nanjing University, Nanjing 210093, China Department of Mathematics Beijing Normal University Beijing China Department of Mathematics Nanjing University Nanjing China

First, that prime C~* -algebras with countable primitive ideals are all primitive C*-algebras is proved. Then the proof that prime C~* -algebras with property RR(A) = 0 are all primitive C~*-algebras is given.

Analysis in Theory and Applications 2021年第4期37卷 572-592页

作者： Zied Douzi Bilel Selmi Faculty of Sciences of Monastir Department of Mathematics5000-MonastirTunisia

In this paper,we compare the mutual multifractal Renyi dimensions to the´mutual multifractal Hausdorff and pre-packing *** also provide a relationship between the mutual multifractal Renyi dimensions of orthogonal projection.´of a couple of measures(µ,ν)in R^(n).As an application,we study the mutual multifractal analysis of the projection. of measures.

A　STUDY　OF　SEROTONERGIC　NEURONS　ON　PATHWAY　FROM　THE　MEDULLARYRAPHE　NUCLEI　TO　THE　CEREBELLAR　CORTEX　IN　THE　KITTEN　BY　USING　FLU

引用

Journal of Pharmaceutical Analysis 1995年第1期9卷 19-24页

作者：江赛男

The serotonin-immenoreactive neurons in the medullary raphe nuclei that project to thecerebellar cortex were investigated by means of a combined microsphere retrograde transport withimmunofluorescence *** to microsphere injections into the cerebellar vermis(lobules Ⅴ￣Ⅷ)the cells thus retrogradely labeled were found in all medullary raphe nuclei.78.08% ofthe microsphere-labeled cells were located in the nucleus raphe ***-labeled cellswere prominent in the P10 and P11 section ***-immunoreaective neurons were present primarily in the raphe nuclei and adjacent reticular *** double-labeled by microspheresand serotouin-immunostatning were rare, although there were neurons positive for microsphere orserotonin-immunoreaction *** results imply that the medullary raphe nuclei do not seem to bethe origin of serotonin fibers of the cerebellar vermal cortex(lobulcs Ⅴ￣Ⅷ).

关键词： rapke nuclei cerebellum micresphere serotonin projection.
