Impulsive Higher-order Nonlinear And Functional Problems: Periodic And Semi-linear Impulsive Equations And Coupled Systems (Trends in Abstract and Applied Analysis)

This book focuses on advanced higher-order boundary value problems featuring instantaneous changes (impulses) in unknown functions and their derivatives. It explores novel applications of Laplacian operators, including p-Laplacian and Phi-Laplacian, specifically in discontinuous and impulsive settings — a topic rarely covered in current literature.

The first part addresses nonlinear impulsive boundary value problems, using topological and analytical methods to tackle complex cases such as periodic solutions and unbounded domains. The second part delves into impulsive coupled systems, where multiple unknown functions interact and influence jump conditions, offering new insights into these understudied systems.

Additionally, the book covers functional boundary conditions, generalizing traditional local boundary data to include integral, multi-point, and global constraints, expanding the scope of applications in mathematical modeling.

Ideal for graduate and PhD students, postdoctoral researchers, and professionals in mathematics, engineering, mathematical biology, and applied sciences, this book provides rigorous mathematical tools and methods for solving challenging impulsive differential equations and nonlinear coupled systems.

Sara Perestrelo has both a BSc and an MSc in Physics specializing in Solid-state Physics from the University of Lisbon and is currently enrolled in a PhD in Mathematics at the University of Évora. Apart from her research, Sara has professional experience in high school level teaching in Mathematics and science outreach within the field of Astronomy and Astrophysics. The latter activity still holds in partnership with the Lake Alqueva Observatory. Most of her recent works were produced within the field of Analysis, on Existence and Localization of Periodic Solutions in ODEs, and Discrete Dynamical Systems, on Synchronization of Huygens Oscillators. Currently she is working as a risk analyst at Banco BPI, as a member of the Model Validation team.
