A POSTER ABOUT THE RECENT HISTORY OF FRACTIONAL CALCULUS J. A. Tenreiro Machado 1 , Virginia Kiryakova 2 , Francesco Mainardi 3 Abstract In the last decades fractional calculus became an area of intense re- search and development. The accompanying poster illustrates the major contributions during the period 1966-2010. MSC 2010: 26A33, 05C72, 33E12, 34A08, 34K37, 35R11, 60G22 Key Words and Phrases: fractional calculus, history Preliminary note Clearly, lists such as those assembled in the paper [1] as well as in the present short note, can never be complete, and, besides, there must be selective decisions. We do apologize for all omissions. Moreover, we have not given any judgment on the references in [1]: we limited ourselves to cite (possibly/hopefully) most of them. The progress of fractional calculus The fractional calculus started from some speculations of G. W. Leibniz (1695, 1697) and L. Euler (1730), and it has been developed progressively up to now. A list of mathematicians, who have provided important contri- butions up to the middle of the twentieth century, includes P. S. Laplace 1 Corresponding author
