Project description
Changing the (mathematical) foundations to build a different structure for sameness
Science and engineering are fields that rely heavily on mathematics to establish concrete relationships between various parameters and enable insight into the evolution and systems of parameters over time. Homotopy methods, where homotopy is a property of two mathematical objects that can be continuously deformed one into the other, are useful for solving systems of nonlinear equations relevant to areas including robotics, chemical engineering and circuit theory. Over the last couple of decades, motivic homotopy theory (also called A1-homotopy theory) has been creating quite a stir among the mathematics community. Combining components of algebra and topology, it studies algebraic varieties (solution sets that are the focus of algebraic geometry) from a homotopy theoretic viewpoint. The EU-funded MbHI project is developing new foundations for motivic homotopy theory that will enable its extension to the description of non-A1-homotopy.
Objective
The proposed project is aimed at establishing new foundations of motivic homotopy theory, which enhances Voevodsky's motivic homotopy theory. Voevodsky's motivic homotopy theory is based on A1-homotopy theory, and thus it cannot capture non A1-homotopy invariant phenomena in algebraic geometry such as algebraic K-theory (for singular varieties), topological cyclic homology, logarithmic cohomology, deformation theory, (wild) ramification theory, and so on. Our new foundation is based on projective bundle formula instead of A1-homotopy invariance, so that it has a potential to capture aforementioned non A1-homotopy invariant phenomena. To overcome fundamental difficulties to use projective bundle formula as an input of homotopy theory, we use ``derived correspondence'', which is a derived version of framed correspondence. Another key input is the notion of derived blow-ups, which was used by Kerz, Strunk and Tamme to solve Weibel's conjecture. This project consists of the construction of a new motivic homotopy category and its applications. Applications would include a construction of motivic cohomology (for possibly singular varieties) together with a motivic spectral sequence to algebraic K-theory (Beilinson's conjecture), motivic interpretation of topological cyclic homology, and motivic interpretation of logarithmic cohomology.
