Third International Workshop on
Differential Algebra and Related Topics (DART-III)
November 13-16, 2008, Rutgers University at Newark

Final Announcement

The Third International Conference on Differential Algebra and Related Topics (DART-III) is the third in a series of conferences after DART (2000) and DART-II (2007) on the subject of differential algebra and related topics. Based on the pioneering work of Ritt and foundational research of Kolchin in the last century, differential algebra has evolved into an extremely rich subject in the recent two decades. From traditional studies of differential equations using an algebraic view point, it now has interactions with highly diversified areas of mathematics, ranging from algebraic geometry, combinatorics, and mathematical logic to differential algebraic equations on differential manifolds, Diophantine geometry, and arithmetic differential equations. New and improved differential algebraic methods have been incorporated in many symbolic computation systems. Much progress has also been made in related algebra structures, such as difference algebra, difference and differential schemes, and Rota-Baxter algebra.


Topics. Differential Galois theory, differential schemes, differential algebraic groups, differential algebra and model theory, exterior differential systems, Riemann-Hilbert correspondence, Rota-Baxter algebra, renormalization, integrable systems, computational differential algebra. Analogous topics in difference algebra are included as well. Other topics such as D-module theory, control theory, and applications to non-commutative differential geometry will also be considered in as much as they relate to the above.
