利用算子分块方法研究了具有一般定义域的形式Hamilton算子的可逆性和可逆补,还进一步给出了无穷维Hamilton算子的相关结论.
Using the operator block technique, we investigate the invertibility and the invertible completion of formal Hamiltonian operators (not necessarily bounded) with natural domain. Also, the analogous results for Hamiltonian operators are further presented.
