摘要:In this paper, we introduce the notion of (strongly) 𝘎𝘍-projective modules. We show that a module is projective if and only if it is GF-projective and its Gorenstein flat dimension is at most 1, if and only if it is strongly GF-projective and Gorenstein flat. Moreover, we ...

摘要:We give an elementary proof of the Spivey’s identity for the Bell numbers B(k), and we show that it implies a recurrence relation for ∑ j=0n Sn[j], thus these quantities involving the Stirling numbers of the second kind are linear combination of the B(k).

摘要:In this paper, we introduce the concepts of ψĝ-closed (resp. ψĝ- open) sets in biˇCech closure space and some characterizations and properties are investigated. Further, the concept of ψĝC0 biˇCech spaces and ψĝC1 bi-ˇCech spaces are introduced and their basic prop...

摘要:This paper presents a new procedure and tables for the construction and selection of new attribute acceptance sampling plan called as Quick Switching System of Type-2 with Single Sampling Plan as reference plan using weighted Poisson distribution by Muller's method indexed throug...

摘要:We study the trace of the Laplace transform of exp(t A_nxn) in terms of the Faddeev’s matrices and the characteristic polynomial of A. Our expressions are in harmony with the results of Shui-Hung Hou..

摘要:It is very important in many real life systems to decide when the server should go for a vacation and what type of vacation policy to be adopted for a better performance of the system. In this paper, an M/G/1 retrial queue, where the customer being informed of the system sta...

摘要:The aim of this paper is to introduce the concept of normal (left normal and right normal) seminear-rings. Moreover some related properties of those are investigated. We also characterize such seminear-rings under certain conditions.
