The dynamics of a bound state theory - based on a QED like Lagrangian with fermions coupled to boson fields - has been studied explicitly. Different from the Hamilton approach studied earlier, an additional acceleration term is found, which is spurious for fundamental bound state...

The determination of the number of representations of a positive integer by certain octonary quadratic forms are given in the literature. For instance, the formulas N(12a, 22b, 32c, 62d; n) for the nine octonary quadratic forms are given with a = 1, b = 2, c = 3 and d = 6. Moreov...

The concept of ‘Ψ - Caputo’ fractional derivative is discussed in this article. This method is based on the fractional derivative in Caputo sense of a function with respect to another function Ψ , called kernel. The kernel function Ψ , is any increasing function such that . Expe...

Quadratic forms in four variables over the field 2 are sorted first of all with respect to permutation symmetry. Thereafter it is shown that any such form is equivalent to one of seven such canonical forms. The orthogonal group of each one of these seven forms is obtained. The pa...

In [1], Gyamfi et al. described homological properties in relation to Nakayama Algebras with projectives that satisfied condition Extn (M,N) = 0 for n ≫ 0 ⇐⇒ Extn (N,M) = 0 for n ≫ 0, [1]. The purpose of this paper is to give a similar characterization of Nakayama algebras. In pa...
