Therefore the cohomology of with coefficients in an arbitrary L 1 - m o d u l e may be calculated with use of the complex A • 28 A D° A )A where of 4 i ~ (i0) is defined by the matrix which is the transpose of the matrix described above. If A is a thread module then the complex (10) is decomposed into the sum of complexes of the form 0 where •.. generated correspondingly (that is by {£+~[~-Z) ) and D~ IL' is defined by a scalar matrix with the entries (remind that 4 ~ ~'+O)',-l- "=~" ~-" (~+-'q/')--Q-(+-(q/-'~'))) Turn now to the spectral sequence to a filtration in the module tration in the complex 8~A~ from Section 2.
