DESCRIPTION:\n\n\n      \n      \n\n\n\nMathematical Sciences Department\nL
 evi L. Conant Lecture\nTitle: Fractional derivatives: Fourier, elephants, 
 memory effects, viscoelastic materials, and anomalous diffusions\nSpeaker:
  Pablo Raúl Stinga, Iowa State University\nAbstract: We all know how to co
 mpute one, two, three or more derivatives of differentiable functions, and
  how to integrate them. When calculus was being discovered, Leibniz introd
 uced the idea of defining the derivative of order 1/2 of a function. Years
  later, Fourier came up with a general definition of a fractional derivati
 ve that would work for any function. We will unpack Fourier’s definition o
 f fractional derivative (and fractional integral) using modern methods and
  present the Fundamental Theorem of Fractional Calculus. We will then show
  how fractional differential equations arise naturally in models of data s
 cience, viscoelastic materials in mechanics and anomalous diffusions in ph
 ysics.\nBio: Pablo Raúl Stinga earned his Licenciatura en Ciencias Matemát
 icas degree at Universidad Nacional de San Luis, in San Luis, Argentina (2
 005). He earned his Máster en Matemáticas y Aplicaciones (2007) and his Do
 ctorado en Matemáticas Doctor Europeus under the direction of José L. Torr
 ea at Universidad Autónoma de Madrid, Spain (2010). He held postdoctoral r
 esearch positions at Universidad de Zaragoza, Spain (2010) and Universidad
  de La Rioja, Spain (2011–2012). During the period 2012–2015, he was the R
 .H. Bing Fellow in Mathematics No.1 Instructor at The University of Texas 
 at Austin, USA, where he worked as a postdoctoral researcher under the sup
 ervision of Luis A. Caffarelli. He is currently Professor at Iowa State Un
 iversity, USA. His research interests are in analysis, partial differentia
 l equations and nonlocal fractional equations.\n
