Abstract

Motivic Geometry is an amalgam of the classical areas of mathematics called algebra and geometry. The subject was primarily invented to solve long-standing mathematical conjectures via innovative interactions between traditionally different areas of mathematics. Mathematicians are only starting to understand the ramifications of this new perspective initiated in the late 1990s. The CAS project advanced the topics of motivic homotopy theory and its logarithmic version, an emerging algebro-geometric version of Poincare’s conjecture, and quadratically enriched enumerative geometry. Specific milestones in the project include an explicit calculation of the second universal invariant of the motivic spheres, the construction of punctured motivic neighborhoods, stable motivic homotopy types at infinity as a step towards a motivic Poincare conjecture, and complete algebraic counts of enumerative problems. Another development in the project is the ongoing foundational work on logarithmic motivic homotopy theory.
