We present the coupling of torsion scalar T and trace energy-momentum tensor $\mathcal {T}$ , which produces new modified f ( ) $f(T,\mathcal {T})$ gravity. Moreover, we consider functional form = α + β 2 {T}) =\alpha \mathcal {T}+\beta T^2$ where are free parameters. As an alternative to a cosmological constant, theory may offer theoretical explanation late-time acceleration. The recent observ...

in this note, we introduce the concept of a fuzzy filter of a blalgebra,with respect to a t-norm briefly, t-fuzzy filters, and give some relatedresults. in particular, we prove representation theorem in bl-algebras. thenwe generalize the notion of a fuzzy congruence (in a bl-algebra) was definedby lianzhen et al. to a new fuzzy congruence, specially with respect to a tnorm.we prove that there i...
