Mean ergodic type theorems
(Ankara Üniversitesi Fen Fakültesi, 20190801)Let T be a bounded linear operator on a Banach space X . Replacing the Ces\`{a}ro matrix by a regular matrix A = ( a n j ) Cohen studied a mean ergodic theorem. In the present paper we extend his result ... 
Generalizations of some results on generalized polynomial identities
(Ankara Üniversitesi Fen Fakültesi, 20190801)Motivated by the generalized polynomial identities in [1] and [5], our aim is to generalize some of the results in these works. Precisely, we extend the result in [1] on commuting values of the same generalized derivations ... 
Decision making for portfolio selection by fuzzy multi criteria linear programming
(Ankara Üniversitesi Fen Fakültesi, 20190801)In daily life events, there are many complexities arising from lack of information and uncertainty. Fuzzy linear programming model has been developed to reduce or eliminate this complexity. Fuzzy linear programming is the ... 
Algebraic structure of square matrices over residuated lattices
