1) Initial-boundary value problems for the complex Ginzburg-Landau equation on a bounded domain is discussed when we take the initial values from the Lebesgue space L-p (p>2). As a corollary we can reformulate the result of Ginibre-Velo (1997) in which the initial values are taken from the Sobolev space H-1. In addition we can weaken the restriction on the exponents of the power of the nonlinear term if we take the initial values from H-m (m is a integer greater than or equal to 2). The stationary problems are also considered. (2) We have presented a new sufficient condition which guarantees the quasi-m-accretivity of Schroedinger operators with singular first-order coefficients. The result is regarded as an improvement of that by late Professor Tosio Kato. (3) We have obtained the estimates of the eigenfunctions e_n of the Laplace operator on a bounded domain. | (e_n) (x) | is bounded by the constant multiple of the eigenvalue to the power of N/4. This exponent with N=1 appears in the estimates of the eigenfunctions of the Schroedinger operator of the one-dimensional harmonic ocsilltor.

1)讨论了有界域上复Ginzburg-Landau方程的初边值问题，其初值取自勒贝格空间L-p(p&gt；2)。作为推论，我们可以重新表述Ginibre-Velo(1997)的结果，其中的初值取自Sobolev空间H-1。此外，如果取H-m(m是大于或等于2的整数)的初值，则可以减弱对非线性项的幂的指数的限制。文中还考虑了定常问题。(2)给出了一阶奇异系数薛定谔算子的拟m-增生性的一个新的充分条件。这一结果被认为是已故加藤东彦教授的改进。(3)得到了有界域上Laplace算子的本征函数e_n的估计。|(E_N)(X)|由本征值的N/4次方的常数倍数所限定。这个N=1的指数出现在一维谐振子的薛定谔算符的本征函数的估计中。
