%X Put forward the concepts of proper concept lattice and attributes reduction of concepts and proper concept lattices(including concept lattices)in formal contexts.Defined the characteristic functions of concepts and proper concept lattices(including concept lattices),advanced the theorems of attributes reduction based on them,and educed the idiographic methods of attributes reductions.At the same time,studied the relations between attributes under the different attributes reduction,had perfected the theory o...
