Acerca del autor:

Born in Madrid, Spain, in 1964, Manuel Mañas obtained his PhD in Physics in 1987 from the Complutense University of Madrid (UCM). Currently holding the position of full professor in Theoretical Physics at UCM, he has also served as a faculty member at the Instituto de Ciencias Matemáticas. Mañas has demonstrated his commitment to the academic sphere by being an active member of the Government Board of the Royal Spanish Mathematical Society.
He has served as a visiting professor at several prestigious international institutions, including Johannes Kepler Linz University (Austria), University of Aveiro (Portugal), University of California at Berkeley (USA), China University of Mining and Technology (Beijing, China), Université Catholique de Louvain (Belgium), SISSA (Trieste, Italy), La Sapienza (Italy), and Leeds University (UK).
Mañas’ dedication to teaching is evident in his comprehensive curriculum. His instructional portfolio spans a diverse array of topics in mathematical physics. He specializes in teaching courses related to partial differential equations, with a particular focus on their applications in physics, encompassing boundary value problems. Moreover, his teaching extends to the fundamental principles of complex analysis in one variable and their practical applications. Furthermore, Mañas has shared his expertise through postgraduate courses, imparting knowledge on a wide range of advanced topics. These include functional analysis, Lie group theory, integrable systems, and orthogonal polynomials.
With 127 scientific publications to his name, Manuel Mañas’ research primarily focuses on mathematical physics and applied mathematics. His expertise spans various areas, with notable contributions in the theory of integrable systems, the field of orthogonal polynomials, and the theory of special functions. Of late, he achieved a significant breakthrough by establishing a spectral theorem similar to Favard’s for bounded banded operators, effectively extending the well-known spectral Favard theorem for Jacobi matrices. His research also encompasses investigations into random walks and Markov chains beyond birth and death processes. His contributions also include foundational work in discovering the Lax pair for the Krichever–Novikov equation, creating Darboux transformations for the nonlinear Schrödinger equation, and identifying new solutions for supersymmetric integrable systems.
Mañas has demonstrated effective leadership and administrative skills throughout his career. He has held several key administrative roles, such as Vice Chancellor of Innovation, Vice Dean, and Coordinator of the Doctoral Program in Physics.

Born in 1949 in Tolosa, Spain, Luis Martínez-Alonso earned his PhD in Physics in 1975 from the Complutense University of Madrid (UCM). Over the course of more than 40 years as a full professor at UCM, he imparted mathematical methods to physicists. His teaching portfolio encompassed a wide range of mathematical physics subjects, from fundamental courses in linear algebra and calculus to specialized classes in functional analysis, partial differential equations, and Lie group theory.

Throughout his career, he has profoundly influenced several generations of physicists and earned recognition as an esteemed educator. Additionally, he served as the Director of the Theoretical Physics department at UCM during various periods. He currently holds the title of emeritus professor at Complutense University of Madrid.
Martínez Alonso has also held visiting professorships at several prominent institutions, including the Universities of Montpellier and Paris VI in France, as well as Rome I and III in Italy, Lecce (Italy), and the Newton Institute at the University of Cambridge (UK).

He boasts authorship and co-authorship of over 120 research articles spanning topics such as symmetries, conservation laws, integrable nonlinear differential equations, matrix models, and mathematical aspects of cosmology. His notable research achievements include proving the converse of the Noether theorem, providing a counterexample to the Gel’fand–Kirillov conjecture on the enveloping algebras of Lie groups, formulating the soliton-radiation interactions in nonlinear integrable models (both continuous and discrete), establishing hierarchies of nonlinear integrable models associated with Schrödinger spectral problems featuring energy-dependent potentials, and contributing to the development of the four-dimensional integrable model known as the Martinez-Alonso and Shabat model Currently, his research interests center on inflationary quantum cosmology and the foundations of quantum physics.
