On the cofiniteness of generalized local cohomology modules
Let be a commutative Noetherian ring, an ideal of and ,
two finitely generated -modules. The aim of this paper is to investigate the
-cofiniteness of generalized local cohomology modules \displaystyle
H^j_I(M,N)=\dlim\Ext^j_R(M/I^nM,N) of and with respect to . We
first prove that if is a principal ideal then is -cofinite
for all and all . Secondly, let be a non-negative integer such
that \dim\Supp(H^j_I(M,N))\le 1 \text{for all} j Then is
-cofinite for all and \Hom(R/I,H^t_I(M,N)) is finitely generated.
Finally, we show that if or then is
-cofinite for all .Comment: 16 page
Optimisation Of Processing Parameters Of Resin System In Development Of Adf Radome Fairings For Tu-142m Aircraft
This report highlights the optimization processing parameters for the resin system used in the fabrication of radomes for the TU-142 M aircraft . The radomes were fabricated using the standardised RIT process developed in-house with optimized parameters
