Higher homological algebra was introduced by Iyama. It is also known as n-homological algebra where n > 2 is a fixed integer, and it deals with n-cluster tilting subcategories of abelian categories. All short exact sequences in such a subcategory are split, but it has nice exact sequences with n + 2 objects. This was recently formalised by Jasso in his theory of n-abelian categories. There is a...

Motivated by higher homological algebra, we associate quivers to triangulations of even-dimensional cyclic polytopes and prove two results showing what information about the triangulation is encoded in quiver. We first show that cut Iyama Oppermann correspond precisely 2d-dimensional without interior (d+1)-simplices. This implies these form a connected subgraph flip graph. Our second result sho...

This article examines the concept of ecomasculinity--how masculinities and ecologies interact--through lens deep ecology, arguing (following Serpil Oppermann) that Pynchon's postmodernist boundary collapsing informs deep-ecological interconnections for male characters previously embroiled in negative cycles patriarchal dominance. Ecomasculinity is an important emerging within ecocriticism, reco...
