证明了每个空间L2 (I1,∪I2)，其中I1和I2是有限区间，具有复指数的Riesz基，{λk}是实数序列。对n≧3个有限区间的相应问题也得到了部分结果。
It is proved that every space L2 (I1, ∪ I2), where I1 and I2 are finite intervals, has a Riesz basis of complex exponentials , {λk} a sequence of real numbers. A partial result for the corresponding problem for n≧3 finite intervals is also obtained.
