DISCRETE PHENOMENA IN EXISTENCE IN MIXED PROBLEM

【摘要】 <正> F. Treves studied an interesting example and proved that the Cauchy problem has non-trivial solutions if and only if p=1,3,5,…. Wang Guangyin et al. proved the discrete phenomena in existence in the Canchy problem and the Goursat problem of the Treves equation. Wang Chuanfang studied the discrete phenomena in existence in the mixed problem of the first boundary. Now we shall discuss the mixed problem of the second boundary.更多还原
