Homological Algebra Of Semimodules And Semicont... 🆕

Frequently used to study the global sections of semimodule sheaves on tropical varieties. 3. Semicontinuity and Stability

A key feature is the adaptation of and Tor functors. Since you cannot always "subtract" to find boundaries, homological algebra here often uses: Homological Algebra of Semimodules and Semicont...

The rank or homological dimension of a semimodule often drops at specific points of a parameter space, mirroring the behavior of coherent sheaves in algebraic geometry. Frequently used to study the global sections of

Unlike traditional modules over a ring, are defined over semirings (like the Homological Algebra of Semimodules and Semicont...

The "Semicontinuity" aspect typically refers to the behavior of dimensions (like the rank of a semimodule) under deformations.
