  Título: Mountain Pass solutions for an entire semipositone problem involving the Grushin operator.

  Conferenciante: Paolo Malanchini (Università degli Studi di Milano-Bicocca).

  Resumen:

  For \(N\ge 3\) we study the following semipositone problem$$ -\Delta_\gamma u = g(z) (f(u)- a) \quad \hbox{in $\mathbb{R}^N$}, $$ where \(\Delta_\gamma\) is the Grushin operator $$ \Delta_ \gamma u(z) = \Delta_x u(z) + |x|^{2\gamma} \Delta_y u (z) \quad (\gamma\ge 0), $$ \(g\in L^1(\mathbb{R}^N)\cap L^\infty(\mathbb{R}^N)\) is a positive function, \(a>0\) is a parameter and \(f\) is a continuous function with subcritical and Ambrosetti-Rabinowitz type growth and which satisfies \(f(0) = 0\). Depending on the range of \(a\), we obtain the existence of mountain pass solutions in a suitable Sobolev space associated to the Grushin operator. Finally we study the positivity of the solutions in the degeneracy set.

  • IMAG Functional Analysis Seminar
  • Title: Álgebras de Lie reales simples y sus ideales internos
  • By Antonio Fernández López (Universidad de Málaga)
  • Abstract: Sea L un álgebra de Lie sobre los complejos del tipo A_l, B_l, C_l, o D_l. En esta charla clasificamos las formas reales de L y sus ideales internos, adoptando un punto de vista distinto del habitual. Derivamos la clasificación de las formas reales, g, de L de dos teoremas de Herstein traducidos a un lenguaje geométrico, lo que nos permite describir los ideales internos en términos algebraicos y geométricos.

  Description: The aim of the conference is to bring together researchers from a wide variety of backgrounds who are concerned with the mathematics of shape generation in the framework of architecture and structural design. These two fields have indeed undergone major developments thanks to discrete differential geometry and integrable system. At the heart of the subject is the discretisation of shapes, their resulting constructional and mechanical properties as well as the methods for deforming these shapes conserving these properties. Topics of particular interest are: the discretization of surfaces by quad planes with remarkable features, their kinematic or mechanical rigidity, shape duality in all its forms, to name of few.

  May 25 to May 30, 2025

  The Institute of Mathematics at the University of Granada will host the “Functional and Metric Analysis and their Interactions” workshop at the University of Granada (IMAG) in Spain, from May 25 to May 30, 2025.

  Beyond mere mathematical curiosity, the study of discrete spaces and their geometry is of great importance to a broad range of scientists including theoretical computer scientists working with data analysis and signal processing, economists interested in transportation theory, and physicists who use certain observable algebras in order to better describe topological phase transitions. In this context, functional analysis can provide the ideal machinery needed to linearize questions which are a priori discrete in nature and allow scientists to obtain useful models for their concrete problems. In the last few decades, the study of metric spaces under a functional analytical point of view has increased tremendously and we currently have many different ways of coding the geometry of certain spaces such as using transportation cost Banach spaces or Roe algebras and their many variants. The goal of this conference is to bring together world experts in these topics to a unique event which will allow mathematicians from a very diverse background to interact with each other and provide new and exciting links between seemingly separated mathematical fields. The conference will also contain a large number of junior researchers and students so that the field can keep on being developed and new professionals are trained.

  The Institute of Mathematics at the University of Granada(IMAG) in Granada, Spain, and the Banff International Research Station for Mathematical Innovation and Discovery (BIRS) in Banff, are collaborative Canada-US-Mexico ventures that provide an environment for creative interaction as well as the exchange of ideas, knowledge, and methods within the Mathematical Sciences, with related disciplines and with industry. The research station in Banff is supported by Canada’s Natural Science and Engineering Research Council (NSERC), the U.S. National Science Foundation (NSF), and Alberta Technology and Innovation.
