	Adjoint and selfadjoint Lie-group methods - Zanna, Eng, Munthe-Kaas (ResearchIndex)
		The definition of adjoint of a numerical method is thus subordinate to the method itself and the choice of the coordinate map.
		We study Lie-group numerical methods and their adjoint, and define selfadjoint numerical methods.
		The latter are defined in terms of classical selfadjoint Runge--Kutta schemes and symmetric coordinates, based on a geodesic midpoint or on a flow midpoint.

		In particular, it was proved that the minimal support of absolutely continuous part of the measure associated to Herglotz-Nevanlinna matrix-valued function is invariant under some class of linear fractional transformations.
		The new version of the well known Krein's resolvent formula in terms of von Neumann's parametrizations of selfadjoint extensions of symmetric operator was obtained as well.
		Recently we solved the von Neumann problem about parametrization of all nonnegative selfadjoint extensions of a nonnegative, densely defined symmetric operator in terms of his classical formulas and pointed out applications to the descriptions of all nonnegative selfadjoint quantum hamiltonians in point interaction problem with m points of interaction.

	Reflection operators in quantum groups (Site not responding. Last check: 2007-10-31)
		A reflection operator is by definition a unitary with square equal to I. If such an operator anticommutes with a symmetric operator, the latter has equal deficiency indices.
		This simple remark is very important when one considers quantum group with function algebra generated by selfadjoint elements.
		If $a$ is a selfadjoint generator then $\Delta(a)$ is symmetric, but not selfadjoint in general.

	Notes - Math 423-500 (Narcowich)
		A matrix is selfadjoint or Hermitian if it is equal to its own adjoint.
		Theorem: The eigenvalues of a selfadjoint matrix are real and the eigenvectors corresponding to distinct eigenvalues are orthogonal.
		Theorem: Every selfadjoint matrix has an orthonormal basis relative to which it is diagonal.

		Separation of independent variables is a well-known technique for ``solving'' PDEs, or more precisely, for reducing their solution to a family of ODEs containing parameters coupling them.
		In a spectral theoretical context, the following natural question arises: Suppose that a formally selfadjoint elliptic differential expression has been decomposed into a family of formally selfadjoint ODE differential expressions (coupled by parameters) by separation of variables, and that selfadjoint extensions of the corresponding minimal ODE operators have been selected.
		Under which condition is there a ``natural'' way of using these selfadjoint operators to define a selfadjoint realization of the given elliptic expression?

	AMCA: J-selfadjoint ordinary differential operators similar to selfadjoint operators by Ilia Karabash (Site not responding. Last check: 2007-10-31)
		is similar to a selfadjoint operator if p(t) is a nonnegative polynomial with at most one real root.
		It is based on the Carleson embedding theorem and the similarity criterion which has been obtained by S. Naboko [3] and M.

	Atlas: Canonical systems with selfadjoint interface conditions by Henrik Winkler (Site not responding. Last check: 2007-10-31)
		Two-dimensional canonical systems of differential equations Jy'=-zHy on the real line are considered with selfadjoint interface conditions at 0.
		If one or both of the intervals around 0 are H-indivisible the interface conditions which give rise to selfadjoint relations (multi-valued operators) are determined.
