Three Portraits of S. Kovalevsky: Interpretation of S. Kovalevsky’s life and creativity in the works by P. Ja. Kochina, A. C. Leffler and A. Munro This research puts forward the hypothesis that S. Kovalevsky was an example of a multifaceted talent: an outstanding mathematician, writer and public figure simultaneously. As such, the basis of the phenomenon that is S. Kovalevsky is the ingenious synthesis of the various facets of creativity.  An attempt was made to achieve a better understanding of the multifaceted life and creativity of S. Kovalevsky though a comparative study of the perceptions of Kovalevsky put forward by the Swedish writer, A.C. Leffler (1892), and that of the Russian biographer, P. Ja. Kochina (1981), and that of the Canadian writer, A. Munro (2009), Nobel laureates in literature 2013. Similarities and differences in the interpretations and understanding of the life and creativity of S. Kovalevsky between the Swedish, Russian and Canadian authors were identified and an important part was to define which image of S. Kovalevsky appears in the analysis of the authors. Another essential component was to identify which image dominates, that of Kovalevsky as a mathematician, as a writer or as a public figure. A table, containing the results of a comparative analysis using the maximum number of identified, scientifically sound parameters, is also presented in the study for a clearer picture of the perception of S. Kovalevsky’s image presented by the three writers. Twenty-four such comparative parameters were identified. The article concludes with possible prospects for further research on the subject.
