Abstract
Relativistic fluid dynamics is a versatile and powerful effective theory, essential for understanding physical systems under extreme conditions of temperature and density. It plays a pivotal role in studying phenomena such as the Quark-Gluon Plasma (QGP) produced in heavy-ion collisions, the early universe's matter, neutron star mergers, and black holes within the framework of holographic gauge-string duality. Despite its long history and broad applicability across disciplines, the scope and foundations of relativistic hydrodynamics remain active areas of ongoing research. This workshop aims to bring together physicists from diverse fields: those applying relativistic hydrodynamics to heavy-ion phenomenology and astrophysics, alongside researchers focused on its theoretical foundations. By fostering a collaborative and interdisciplinary environment, the goal is to promote a synergistic exchange of ideas from these complementary areas, accelerating progress on pressing issues in relativistic hydrodynamics.

Topics
• Quantum effects and effective field theories for hydrodynamics
• Heavy ion collisions and hydrodynamics at high energy and near the QCD critical point
• Spin and hydrodynamics
• Stability and causality in hydrodynamics
• General relativity and hydrodynamics
• Bootstrap techniques and gauge/gravity duality for hydrodynamics
