    Расширение скаляров и гомологии
    Если имеется гомоморфизм колец R \to S, то как известно, по нему строится функтор расширения скаляров ModR \to ModS. Eсли применить этот функтор к цепному комплексу свободных R-модулей, получится цепной комплекс свободных S-модулей. Если R - кольцо главных идеалов, то гомологии этих комплексов связывает теорема об универсальных коэффициентах.

    Так вот вопрос - а что можно сказать, если R - не PID (например групповое кольцо от Z^n)? А будет ли легче, если интересны только старшие гомологии? А если S - поле, это никак не облегчит задачу?

    REVIEW: Ved Buens Ende - Written in Waters (1995, Misanthropy)



    In the mid to late 90s there was a popular infliction in Norway of
    calling anything that somehow doesn't fit in the mold of a specific
    genre, an avantgarde. Such a classification has some merits, however
    the Norwegians within a certain scene got to use the term avantgarde
    extremely liberally. The singer cannot hit a note? That's avantgarde.
    The drummer cannot keep time? That's avantgarde. The band knows nothing
    about song structure and composition? That's avantgarde.

    Those who followed the development of the Scandinavian black metal in
    the 90s readily remembers many musical miscarriages stemming from throwing
    a wrench at the known notions of music, or whatever might be construed as
    such by those involved.

    The album in question released in 1995 (before anything of this sad
    nature in my memory) perhaps receives the credit for starting the
    trend. Those versed in the black metal lore may recall that throughout
    the history of the genre, a (pseudo)intellectualism was one of the key
    ingredients of the ideology and pose. At some point somebody decided
    to crank the knob of the latter to the far right, make a bunch of
    references to the cultural legacy of grown-ups and see if the audience
    swallows what comes out of it. Judging from the rating in Metal Archives,
    the trick worked.

    On "Written in Waters", the only full-length album of thankfully short-
    lived project, members of Manes and Dodheimsgard do exactly that.
    Technically speaking, this is rooted in black metal with everything
    one expects to see in it by 1995. Avantgarde leanings or not, this was
    a wise move as the BM scene in that year was hot. The BM base is liberally
    strewn with snippets of non-black-metal music, primarily leftovers from
    70s, mostly post-Crimson prog rock. Occasionally, jazz parts kick in.
    And all of this lavishly sprinkled with vocal exercises courtesy
    of Carl-Michael Eide, which is the worst part of the deal.
    I've seen many lousy attempts at vocalization in my time, and must admit
    that this is a prize-winning one. The definition of Sir Arthur Conan Doyle,
    "is there a cat or something stuck in a chimney" describes the aural
    experience pretty accurately. Let's face it: Carl-Michael plainly cannot
    sing, in any possible definition of the term. Varg can, Vidar can,
    Calt-Michael cannot. Based on this outing I'd place him at the second
    rank of bad singers, second only to Keiji Haino, and that's a big
    achievement of sorts.

    While awful singing being the worst offense committed by the crew it is
    certainly not the only one. The music is devoid of any dynamics or inner
    logic whatsoever. Both metal and non-metal parts follow one another for
    no apparent reason. Each part taken separately is executed and recorded
    competently, but are mostly un-engaging and tedious on their own, and
    completely lose their appeal and purpose when thrown n a seemingly random
    sequence. Chaotic songwrighting can be executed tastefully and to a great
    deal of dramatic effect, however this is certainly not the case. By the
    time the album reaches its half it becomes damn annoying. For those who
    has patience of sitting though an almost an hour long ordeal there is a
    short reward of a free jazz piece towards the end of the "Remembrance of
    Things Past". Apart from that none of the compositional components are
    particularly worth attention as to that date there were lots of better
    examples in any field touched by this record. The only question worth
    pondering is how this pile of crap ended up being praised as an avantgarde
    masterpiece.

    You will do yourself a favor by avoiding this album. Those brave souls
    who have an hour of their life to waste can form their own opinion here.
