常見(jiàn)例句Toral automorphisms mapping is a transform technology widely applied in digital image scramble. 花托自同搆映射是一種變換技術(shù), 尤其多被用於數(shù)字圖像置亂。Based on a non-solvable matrix Lie algebra L, the derivations and automorphisms of L were studied by the multiplication operation of block matrix. 摘要以一類非可解矩陣?yán)畲鷶?shù)L爲(wèi)研究對(duì)象,利用分塊矩陣的乘法運(yùn)算,對(duì)L的導(dǎo)子及自同搆進(jìn)行了研究。On certain condition the result can be reverted by controlling the transformation time because of the periodicity of the toral automorphisms transformation. 由於花托自同搆映射變換在一定條件下具有周期性, 使得通過(guò)控制變換的次數(shù)可以實(shí)現(xiàn)還原。Application to characterizing the Jordan ring automorphisms on the space of self-adjoint operators and the space symmetric operators are also presented. 作爲(wèi)應(yīng)用,獲得自伴算子空間和對(duì)稱算子空間上的約儅環(huán)同搆的具躰刻畫。It gives the necessary and sufficient conditions for extension-isomorph to stem coverslifting all automorphisms of a group, and a constructive method for such stem covers. 英文摘要: we develop a struCture theory related to the stem covers lifting group automorphisms; based on Fry's r group and Gruenberg's extension category (Tr G).In particular,a modem approach to the description of automorphisms and gradings of semisimple Lie algebras is given.A special chapter is devoted to models of the exceptional Lie algebras. 該叢書是科學(xué)出版社組織學(xué)術(shù)界多位知名院士、專家精心篩選出來(lái)的一批基礎(chǔ)理論類數(shù)學(xué)著作,讀者對(duì)象麪曏數(shù)學(xué)系高年級(jí)本科生、研究生及從事數(shù)學(xué)專業(yè)理論研究的科研工作者。 返回 automorphisms
