What is another word for homological projections?
Pronunciation: [hˌɒməlˈɒd͡ʒɪkə͡l pɹəd͡ʒˈɛkʃənz] (IPA) 
Homological projections are an important concept in mathematics that describe a way of projecting one mathematical object onto another in a way that preserves certain properties. Some synonyms for homological projections include cohomology operations, spectral sequences, and algebraic topology. Cohomology operations are a type of homological projection that describe certain transformations of cohomology classes. Spectral sequences are another type of homological projection that are used to compute the homology and cohomology groups of a mathematical space. Algebraic topology is a related field of mathematics that studies the properties of spaces that are preserved under certain types of homological projections.
