- (essentials self-adjointness)
We consider a formally self-adjoint elliptic differential operator in ℝn, denoted by τ. T0 and T are operators given by τ with specific domains. We determine conditions under which T0 is essentially self-adjoint, introducing the topic by means of a brief historical survey of some results in this field.
In Part I, we consider an operator of order 4, and in Part II, we generalise the results obtained there to ones for an operator of order 2m. Thus, the...Expand abstract
