In some applications the matrix B has to be elementwise nonnegative. If such a matrix exists, A is called completely positive. The smallest number of columns of a nonnegative matrix B such that A=BB[symbol] is known as the cp-rank of A. This invaluable book focuses on necessary conditions and sufficient conditions for complete positivity, as well as bounds for the cp-rank. The methods are combinatorial, geometric and algebraic. The required background on nonnegative matrices, cones, graphs and Schur complements is outlined.MatricesElectronic books.Matrices.512.9/434Berman Abraham42972Shaked-Monderer Naomi906214MiAaPQMiAaPQMiAaPQBOOK9910454295503321Completely positive matrices2026800UNINA00924nas 2200349 c 450 991089356280332120240201115343.0(CKB)5280000000199506(DE-599)ZDB2763658-6(DE-101)1049228227(EXLCZ)99528000000019950620140325a20069999 |y |spaur|||||||||||txtrdacontentcrdamediacrrdacarrierÁgora revista estudiantil del Centro de Estudios Internacionales de El Colegio de MéxicoMéxcio2006-Online-RessourceGesehen am 05.03.2019ÁgoraZeitschriftgnd-content3207,36ssgn0204DE-1019001JOURNAL9910893562803321Agora801747UNINA
