Preface

The opening of the eleventh International Youth Scientific School-Conference "Theory and Numerical Methods for solving Inverse and ill-posed Problems" was held on August 26, 2019 at Novosibirsk State University. The first ten school-conferences, held from 2009 to 2018, showed the relevance and scientific significance of the chosen subject [1,2,3]. Over the past years, researchers, graduate students and undergraduates from Russia, Belarus, Ukraine, Kazakhstan, Uzbekistan, Kyrgyzstan, as well as from China, the USA, Germany, France, Italy, Japan, the UK, Brazil, Malaysia took part in the school-conferences. For 10 years, representatives of 78 universities, 134 research institutes and more than 20 companies (Total, Baker-Hughes, Schlumberger, Rosneft and others) participated actively at school-conferences. The Conference continued until September 4. The participants were very interested in the reports of academicians S. K. Godunov (Sobolev Institute of Mathematics, Novosibirsk), M. A. Guzev (Institute of Applied Mathematics, Vladivostok), I. A. Taimanov (Sobolev Institute of Mathematics, Novosibirsk), E. E. Tyrtyshnikov (Marchuk Institute of Numerical Mathematics, Moscow), corresponding members of the RAS V.V. Vasin (Krasovsky Institute of Mathematics and Mechanics, Ekaterinburg), S. I. Kabanikhin, G. A. Mikhailov (Institute of Computational Mathematics and Mathematical Geophysics, Novosibirsk ), V. G. Romanov (Sobolev Institute of Mathematics, Novosibirsk).
