Essential self-adjointness of strongly singular homogeneous polyharmonic operators
Fritz Gesztesy, Markus Hunziker
We consider essential self-adjointness of strongly singular, homogeneous, polyharmonic operators of the form \[ T_m = \left((-Δ)^m + c|x|^{-2m}\right)\big|_{C_0^{\infty}(\mathbb{R}…

Essential self-adjointness of even-order, strongly singular, homogeneous half-line differential operators
Fritz Gesztesy, Markus Hunziker, Gerald Teschl
We consider essential self-adjointness on the space of even order, strongly singular, homogeneous differential operators associated with differential exp…
