Henrique Fernandes de Lima was born in Fortaleza, Brazil, and graduated in Mathematics from the Federal University of Ceará (Brazil), completed his Master”s degree in Mathematics and obtained his Ph D in Mathematics also from the Federal University of Ceará (Brazil), and has been a professor in the Department of Mathematics at the Federal University of Campina Grande (Brazil) since 2004, where he regularly teaches postgraduate courses on Differential Geometry, Riemannian Geometry, Isometric Immersions and Submanifolds Theory. Author of several research articles, Henrique F. de Lima has been awarded a CNPq Research Grant in Differential Geometry since 2013. Since joining the Federal University of Campina Grande, Henrique F. de Lima has also dedicated himself to training master students and doctors in Mathematics. Giovanni Molica Bisci is currently full professor of Mathematical Analysis at the San Raffaele University of Rome (Italy). He got his Ph D in 2004 at the University of Messina. In his career, he has been an assistant professor at the Mediterranea University of Reggio Calabria (Italy) and in 2018 became an associate professor at the University of Urbino Carlo Bo (Italy). His research interests are nonlinear partial differential equations, variational and topological methods in Nonlinear Analysis, and Differential Geometry. He published more than 140 papers in high level international mathematical journals and two monographs.  In 2019 he was a Highly Cited Researcher (Thomson Reuters). Since 2020 he is in the World’s Top 2% Scientists List – Stanford University.
