The class of n-entire operators
(IOP Publishing, 2013-01)
We introduce a classification of simple, regular, closed symmetric operators with deficiency indices (1, 1) according to a geometric criterion that extends the classical notions of entire operators and entire operators in ...
Conservation laws for non-potential operators
(1999-12-01)
A study was developed in order to build a function M invariant in time, by means of Hamiltonian's formulation, taking into account the equation associated to the problem, showing that starting from this function the equation ...

Trace operators of the bi-Laplacian and applications
(OXFORD UNIV PRESS, 2021)
We study several trace operators and spaces that are related to the bi-Laplacian. They are motivated by the development of ultraweak formulations for the bi-Laplace equation with homogeneous Dirichlet condition, but are ...
Mathematical optimisation techniques applied to power system operation and planning
(2007-10-29)
Nowadays, power system operation becomes more complex because of the critical operating conditions resulting from the requirements of a market-driven operation. In this context, efficient methods for optimisation of power ...

Owa-based aggregation operations in multi-expert MCDM model
(Academy of Economic Studies, 2017)
This paper presents an analysis of multi-expert multi-criteria decision making (ME-MCDM) model based on the ordered weighted averaging (OWA) operators. Two methods of modeling the majority opinion are studied as to aggregate ...
Prioritized induced probabilistic distances in transparency and access to information laws
(Int. Association for Fuzzy-Set Management and Economy, 2017)
In this paper, a new extension of the ordered weighted average (OWA) operator is developed using four different methods: prioritized operators, induced operators, probabilistic operators and distance techniques. This new ...
Generalized Hamacher aggregation operators for intuitionistic uncertain linguistic sets: Multiple attribute group decision making methods
(MDPI AG, 2019)
In this paper, we consider multiple attribute group decision making (MAGDM) problems in which the attribute values take the form of intuitionistic uncertain linguistic variables. Based on Hamacher operations, we developed ...
