killCycles(...,EndDegree=>...) -- Last homological degree processed by killCycles

Bounds the search depth of killCycles. By default EndDegree => -1 tells killCycles to stop after processing the first degree with nontrivial homology. See EndDegree.

Functions with optional argument named EndDegree:

• acyclicClosure(...,EndDegree=>...) -- Option to specify the degree to stop computing the acyclic closure
• isAcyclic(...,EndDegree=>...) -- Option to specify the degree to finish checking acyclicity
• killCycles(...,EndDegree=>...) -- Last homological degree processed by killCycles
• liftToDGMap(...,EndDegree=>...) -- see liftToDGMap -- Lift a ring homomorphism in degree zero to a DG algebra morphism
• liftToDGModuleMap(...,EndDegree=>...) -- see liftToDGModuleMap -- Lift an image of hom-degree-0 generators to a full DGModuleMap
• minimalModel(...,EndDegree=>...) -- see minimalModel -- Build the minimal DG algebra resolution of a quotient ring
• minimalSemifreeResolution(...,EndDegree=>...) -- Option to specify the last degree at which minimalSemifreeResolution kills cycles
• semifreeResolution(...,EndDegree=>...) -- Option to specify the last degree at which semifreeResolution kills cycles
• toComplexMap(...,EndDegree=>...) -- see toComplexMap -- Construct the ComplexMap associated to a DGAlgebraMap
