H. Chen et Bd. Sleeman, COUNTING FUNCTION ASYMPTOTICS AND THE WEAK WEYL-BERRY CONJECTURE FOR CONNECTED DOMAINS WITH FRACTAL BOUNDARIES, Acta Mathematica Sinica, New Series, 14(2), 1998, pp. 261-276
In this paper, we study the spectral asymptotics for connected fractal
domains and Weyl-Berry conjecture. We prove, for some special connect
ed fractal domains, the sharp estimate for second term of counting fun
ction asymptotics, which implies that the weak form of the Weyl-Berry
conjecture holds for the case. Finally, we also study a naturally conn
ected fractal domain, and we prove, in this case, the weak Weyl-Berry
conjecture holds as well.
