THE WELLPOSEDNESS OF ABSTRACT CAUCHY PROBLEMAND SEMIGROUPS OF OPERATORS
抽象Cauchy问题的适定性与算子半群

In the case where A is not defined densely and the solutions are exponentiallyunbounded, we consider the wellposedness of the abstract Cauchy Problem and its relation tothe semigroups generated by A. First, we introduce a new concept- C- wellpos
