Matrix polynomial Tm(2sA) can be computed optimally in terms of matrix products using values for m in the set mk={1,2,4,6,9,12,16,20,25,30,…}, k=0,1,…, respectively, see [2, p. 72–74]. The choice of s is fully described in Section 3. After that, in Step 3, we ...
we have that |u_{n}(x)|\leq 1 for all x\in B\backslash{B_{r_{0}}} and for all n\in \mathbb{N}. Therefore, \begin{aligned} \int _{B}\exp \Big(\alpha s|u_{n}|^{\frac{2}{1-\beta}+h(|x|)} \Big)\:dx \leq & \int _{B\backslash B_{r_{0}}}\exp \Big(...

f 1 ( x ) = 1 π ∫ 0 ∞ e ( 1 − x ) y − y log y sin ( π y ) d y . (20) The NEF-EVF F ( μ 1 ) is discussed in the context of EDMs by [17,18,19]. (For simplicity of notation, we have suppressed the dependence of m 1 and V 1 on b = 1 ). No...

In the phase plane (𝑒1𝛼𝛽−𝑒2𝛼𝛽)e1αβ−e2αβ), 𝑆=0S=0 represents a sliding line passing through the origin having slope of −𝜆−λ. 𝑒1𝛼𝛽˙=−𝜆𝑒1𝛼𝛽e1αβ˙=−λe1αβ (13) First order Equation (13) can be solved to express...
A new four-parameter lifetime distribution called the beta binomial exponential 2 (BBE2) distribution is proposed. Some mathematical features, including quantile function, moments, generating function and characteristic function, of the BBE2 distribution
where υ and ω are two additional parameters whose rule is to increase the skewness and to vary tail weights, and B a , b = ∫ 0 1 t a − 1 1 − t b − 1 d t is the standard beta function. The pdf corresponding to Equation (3) is f x ; υ , ω , ζ = 1 B...
