A Tauberian theorem for Borel-type methods of summability.
A tauberian theorem for Cesàro summability
A Tauberian theorem for distributions
The well-known general Tauberian theorem of N. Wiener is formulated and proved for distributions in the place of functions and its Ganelius' formulation is corrected. Some changes of assumptions of this theorem are discussed, too.
A Tauberian theorem for series of orthogonal rational functions.
A Tauberian theorem for subsequences of functions
A Tauberian theorem with a generalized one-sided condition.
A theorem on generalized absolute Riesz summability

A unilateral boundary-value problem for the rod
A unilateral boundary-value condition at the left end of a simply supported rod is considered. Variational and (equivalent) classical formulations are introduced and all solutions to the classical problem are calculated in an explicit form. Formulas for the energies corresponding to the solutions are also given. The problem is solved and energies of the solutions are compared in the pertubed as well as the unperturbed cases.
