]]>Comment on Algebraic Geometry Belongs to Sheaves by Andrew Macfarlane

Sun, 09 Mar 2014 07:09:58 +0000http://rigtriv.wordpress.com/?p=1509#comment-4720I believe that within a some decades that sheaves will be seen as major tool in the creation of functors (“comparisons”, “measures of structure”) on large systems. For example “Structures of systems 1. Cohomology of manufacturing and supply network-like systems” http://www.tandfonline.com/doi/full/10.1080/03081079.2014.888551.(Int.Jnl.Gen.Sys.)
The analysis of large information and engineering systems (as opposed to building them) has few good analytical tools. Sheaves and their various cohomologies are a way to “integrate” the local and global. This might require the development of (co)homology-like tools that are defined not on groups and rings but perhaps lattices or graphs – the “(co)homology” looking for special objects such as modular lattices or expander graphs. The concept of a Topos might be drafted for logics of such systems with Grothendieck topologies coming from special classes of subsystems. With society becoming more and more dependent on large-scale systems these sprawling logics are ripe for some serious analytical tools.
