Let R be a right noetherian ring and let P<∞ be the class of all finitely presented modules of finite projective dimension. We prove that findimR = n < ∞ iff there is an (infinitely generated) tilting module T such that pdT = n and T⊥ = (p<∞)⊥. If R is an artin algebra, then T can be taken to be finitely generated iff p<∞ is contravariantly finite. We also obtain a sufficient condition for validity of the First Finitistic Dimension Conjecture that extends the well-known result of Huisgen…

Approximations of injective modules and finitistic dimension
Abstract Let Λ be an artin algebra and let the category of finitely generated right Λ-modules of finite projective dimension. We show that is contravariantly finite in if and only if the direct sum E
Finitistic and Representation Dimensions
We prove that the finitistic dimension conjecture, the Gorenstein Symmetry Conjecture, the Wakamatsu-tilting conjecture and the generalized Nakayama conjecture hold for artin algebras which can be
Artin Algebras and Infinitely Generated Tilting Modules
We prove that all n-cotilting R-modules are pure-injective for any ring R and any n ≥ 0. To achieve this, we prove that ⊥1U is a covering class whenever U is an R-module such that ⊥1U is closed under
All tilting modules are of countable type
Let R be a ring and T an (infinitely generated) tilting module. Then T is of countable type; that is, there is a set, 𝒞, of modules possessing a projective resolution consisting of countably
Finitistic dimension and restricted injective dimension
We study the relations between finitistic dimensions and restricted injective dimensions. Let R be a ring and T a left R-module with A = EndRT. If RT is selforthogonal, then we show that rid(TA) ⩽
Igusa–Todorov Endomorphism Algebras
Let A be an artin algebra and A V be a 2-subgenerator such that End A V is Ω3-representation-finite. We prove that, for any M ∈ add A V, the endomorphism algebra of M is an Igusa-Todorov algebra and
Derived equivalence induced by infinitely generated n-tilting modules
Let TR be a right n-tilting module over an arbitrary associative ring R. In this paper we prove that there exists a n-tilting module T ′ R equivalent to TR which induces a derived equivalence between
Infinitely Generated Gorenstein Tilting Modules
The theory of finitely generated relative (co)tilting modules has been established in the 1980s by Auslander and Solberg, and infinitely generated relative tilting modules have recently been studied
Tate-Vogel and relative cohomologies of complexes with respect to cotorsion pairs.
We study Tate-Vogel and relative cohomologies of complexes by applying the model structure induced by a complete hereditary cotorsion pair ($\A$, $\B$) of modules. We show first that the class of


Approximations and the Little Finitistic Dimension of Artinian Rings
Abstract Let R be a ring and let simp-R be a representative set of all simple (right R-) modules. Denote by P P A ,  B ) be the complete cotorsion theory cogenerated by P A -precover of S. We prove
Tilting modules of finite projective dimension
Tilting modules are well known, and are useful in the representation theory of artinian algebras ([2-4, 6, 11]). The purpose of this paper is to define tilting modules of finite projective dimension
The objective of this note is threefold. Firstly, to give a brief historical account of the finitistic dimension conjectures for finite dimensional algebras. Secondly, to give a considerably simpler
Let R be a subring of the rationals. We want to investigate self splitting R-modules G that is Ext R(G; G) = 0 holds and follow Schultz [22] to call such modules splitters. Free modules and
Homological Transfer from Finitely Presented to Infinite Modules
As is well-known, the infinite module theory of certain types of finite-dimensional algebras has a strong similarity to abelian group theory. (See [1] for the case of Kronecker modules, [28] for the
Tilting Modules and Tilting Torsion Theories
Abstract We generalize basic results about classical tilting modules and partial tilting modules to the infinite dimensional case, over an arbitrary ring R. The methods employed combine classical
Tilting Preenvelopes and Cotilting Precovers
We relate the theory of envelopes and covers to tilting and cotilting theory, for (infinitely generated) modules over arbitrary rings. Our main result characterizes tilting torsion classes as the
How To Make Ext Vanish
We describe a general construction of a module A from a given module B such that Ext(B, A) = 0, and we apply it to answer several questions on splitters, cotorsion theories and saturated rings.
