DEOTIA26: Differential Equations, Optimization Techniques, and their Industrial Applications University of Aveiro Aveiro, Portugal, June 3-7, 2026

In an era driven by complex systems and data-intensive challenges, the synergy between differential equations, optimization techniques, and computational modeling plays a pivotal role in shaping scientific and technological progress. The conference DEOTIA26 serves as a premier forum for mathematicians, engineers, and interdisciplinary researchers to share novel insights, theoretical developments, and practical applications that bridge mathematics with real-world problem-solving. The event highlights the transformative power of analytical and numerical methods across diverse domains, emphasizing innovation, efficiency, and sustainability. We mainly consider three key thematic areas:

• Mathematical Foundations: This thematic area explores the theoretical aspects of differential equations, variational principles, and optimization theory. It focuses on analytical methods and the development of new mathematical theoretical directions.
• Computational and Numerical Methods: This thematic area centers on algorithmic approaches and computational strategies for solving complex differential and optimization problems. Topics include numerical simulation, machine learning-assisted optimization, and big data computational systems.
• Solutions and Interdisciplinary Applications: This thematic area focuses on applying mathematical tools to real-world scenarios in engineering, physics, biology, economics, and environmental sciences with special focus in Logistics and Manufacturing —demonstrating how mathematical modeling drives innovation and decision-making across disciplines.

DEOTIA26 will recognize outstanding contributions (e.g., best short paper, best applications, and best student short paper). Most awards will be announced at the Gala Dinner, which will also be a great moment for networking and celebrating together.  (Awards info HERE ,  Coffee breaks, lunches and Gala Dinner menu/info HERE)
