We review the quadratic form of the Laplace operator in spehrical coordinates which acts on the transverse components of vector functions on the $3$-dimensional space. Operators, acting on the parametrizing functions of one of the transverse components with angular momentum 1 and 2, appear to be fourth order symmetric differential operators with deficiency indices (1,1). We develop self-adjoint extensions of these operators and propose correspondent extensions for the initial quadratic form. Eigenfuctions of the extensions in question represent a stable soliton-like solutions of the physical system with the quadratic form being a potential energy.
