Of Semimodules And Semicont... - Homological Algebra

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 semimodule sheaves on tropical varieties. 3. Semicontinuity and Stability Homological Algebra of Semimodules and Semicont...

Constructing resolutions using free semimodules or injective envelopes (like the "max-plus" analogues of vector spaces). The rank or homological dimension of a semimodule

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 here often uses:
