نویسنده
چکیده
Let Λ and Γ be artin algebras and ΛUΓ a faithfully balanced selforthogonal bimodule. We show that the U -dominant dimensions of ΛU and UΓ are identical. As applications to the results obtained, we give some characterizations of double dual functors (with respect to ΛUΓ) preserving monomorphisms and being left exact respectively.

We give in this note a generalisation of the following theorem of Henkin and Passare (cf. [7] and [8]) : Let be Y an analytic subvariety of pure codimension p in a linearly p−concave domain U , and ω a meromorphic q−form (q > 0) on Y ; if the Abel-Radon transform R(ω ∧ [Y ]), which is meromorphic on U * , has a meromorphic prolongation tõ U * containing U * , then Y extends as an analytic subva...

Let Λ and Γ be left and right noetherian rings and ΛU a Wakamatsu tilting module with Γ = End(ΛT ). We introduce a new definition of U -dominant dimensions and show that the U -dominant dimensions of ΛU and UΓ are identical. We characterize k-Gorenstein modules in terms of homological dimensions and the property of double homological functors preserving monomorphisms. We also study a generaliza...

We consider the rational potentials of the one-dimensional mechanical systems, which have a family of periodic solutions with the same period (isochronous potentials). We prove that up to a shift and adding a constant all such potentials have the form U (x) = ω 2 x 2 or U (x) = 1 4 ω 2 x 2 + c 2 x −2 .

In this paper we give a sufficient condition of the existence of W-approximation representations. We also introduce the notion of property (W). As an application to the existence of W -approximation representations we give a relationship among the finitistic dimension conjecture, the Auslander-Reiten conjecture and property (W).
