On the inverse eigenvalue problem for block graphsLin, Jephian C.-H. ; Oblak, Polona, matematika ; Šmigoc, HelenaV delu v celoti rešimo obratni problem lastnih vrednosti za poddružino blokovnih grafov, imenovanih tudi lizike in posplošene uteži. Predstavimo novo metodo, ki uporablja krepke spektralne lastnosti ... matrik. Ta nam dovoljuje, da s pomočjo matrike s spektrom ▫$\sigma$▫ in pripadajočim grafom ▫$G$▫ konstruiramo novo matriko, ki pripada grafu, ki ga dobimo iz grafa ▫$G$▫ z dodajanjem klik, medtem ko se spektru ▫$\sigma$▫ lahko dodamo poljuben seznam lastnih vrednosti. Konstruiramo tudi številne nove spektre za blokovne grafe.Source: Linear algebra and its applications. - ISSN 0024-3795 (Vol. 631, Dec. 2021, str. 379-397)Type of material - article, component part ; adult, seriousPublish date - 2021Language - englishCOBISS.SI-ID - 77244419
