Nelson Merentes

In 1978 Merentes finished his bachelor's degree of Mathematics at Central University of Venezuela and continued his post graduate education taking courses on Economy and Finance, as well as in multifunction techniques for the study of economic problems, completing finally a doctorate in Mathematics with summa cum laude honors, at the Eötvös Loránd University of Budapest (Hungary) (1991).[2]

Merentes developed most of his research and teaching at Central University of Venezuela where he participated as professor, representative and member of various councils and committees.[3]

Merentes also worked extensively in public administration. From 2000 to 2001 he was the Economy and Finance subcommittee's chairman of the National Legislative Committee. He also worked for the Ministry of Finance as deputy minister of Regulation and Control (2000-2001). In 2001 he was appointed as Minister of Finance of Venezuela by President Hugo Chavez. He held that position until the following year, when he was designated as Science and Technology Minister. From that position he was called by President Chavez for the presidency of Social Development Bank (BANDES), a position he left to return to the Ministry of Finance in early 2004. During his second term, took place the creation of the FONDEN, Venezuela's National Development Fund. From April 2009 he became a president of the Central Bank of Venezuela until 2013.[4]

In April 2013 is appointed as Venezuela's Minister of Finance by Nicolás Maduro.[5] In January 2014, he was re-designated as president of the Central Bank of Venezuela.[6]

In 2017, Canada sanctioned Merentes and other Venezuelan officials under the Justice for Victims of Corrupt Foreign Officials Act, stating: "These individuals are responsible for, or complicit in, gross violations of internationally recognized human rights, have committed acts of significant corruption, or both."[7][8]

As a researcher Merentes has published more than 200 scientific papers, including some in specialized mathematical study journals.[9] His field of study was mainly focused on the study of differential equations and Lipschitz continuity. some of his notable contributions include:

• On the Composition Operator in AC[a, b] (1991),
• On the Composition Operator in BV φ[a; b] (1991)
• On Functions of Bounded (p,k)-Variation (1992) (with S. Rivas and J. L. Sánchez)
• Characterization of Globally Lipschitzian Composition Operators in the Banach Space BV²_p [a, b] (1992) (with J. Matkowski)
• Explicit Petree's function of interpolation of the spaces H _p ^s (1993)
• On the Composition Operator between RV_p [a, b] and BV [a, b] (1995) (with S. Rivas)
• Uniformly Continuous Set-valued Composition Operators in the Spaces of Functions of Bounded Variation in the Sense of Wiener (2010) (with A. Azócar, J. A. Guerrero and J. Matkowski)
