Hic, Pavel; Pokorny, Milan There are integral trees of diameter 7. (English) Zbl 1224.05300 Publ. Elektroteh. Fak., Univ. Beogr., Ser. Mat. 18, 59-63 (2007). A graph is integral if its spectrum consists entirely of integers. The authors construct some integral trees of diameter 7 thus answering a question posed in the literature on the existence of such graphs.
