The Quantization of Black Hole's Horizon Area in de Sitter Spacetime

CHEN De-You;YANG Shu-zheng;Institute of Theoretical Physics,China West Normal University;  
Recent researches show that the area spectra take on the form as 8πnl2 p.In this paper,we adopt the Bohr-Sommerfeld quantization condition to quantize the area of event horizon and cosmological horizon of a Schwarzschild de Sitter black hole,and derive that the spectra have the expression as 8πl2 p(n + 1/2).The appearance of ground entropy implies that the black hole cannot evaporate completely and there is the remnant.
