This result is applied to elliptic differential operators with indefinite weights and to certain difference operators.作者: 笨重 時(shí)間: 2025-3-22 04:15 作者: Inflammation 時(shí)間: 2025-3-22 04:44 作者: Hallowed 時(shí)間: 2025-3-22 12:24 作者: 鋼盔 時(shí)間: 2025-3-22 16:41

G. Schild,M. Corbel,P. Corran,P. MinorThis volume is dedicated to Professor Heinz Langer to honor him for his outstanding contributions to mathematics. His results in spectral analysis and its applications, in particular in spaces with an indefinite metric, are fundamental. Five main themes emerge in Heinz Langer’s work, some of them are closely connected or have much in common:作者: collagenase 時(shí)間: 2025-3-25 06:37 作者: 凝視 時(shí)間: 2025-3-25 09:49
