Abstract: | In this paper, the authors continue with the development of an ecological models theory from the viewpoint of mathematical linguistics. The model is considered as a text, which complies with the text theory TT conditions. The variable transformed functions are defined as symbols, the flow equations are defined as words, the flow functions or right hand of differential equations are defined as sentences, resting on the author particular methodology inspired inspired in the system dynamic illustrated in other papers. Three meaning levels are established in each model text and the duality significance or explanation adjustment and significance or interpretation for the observer is defined as getting in the indexes for its indirect measure. A model interpretation theory is given also. |
