The article discusses the mathematical sides of the Hoffman-Wielandt Theorem, a linear algebra formula. The author stressed that Wielandt's mathematical works with group theory and matrix analysis. It has presented the asymptotics of eigenvalues of partial differential operators and inequalities relating the eigenvalues of Hermitian matrics A, B, and A+B.

    The energy of a graph G is defined as the sum of the eigen values of the adjacency matrix of the graph G. We report the upper Bounds for the Laplacian energy of the L(S(Kn)), L(S(Wn)), L(S(Tn,k)) and L(S(Ln)), where L and S stands for line graph and subdivision graph of G. The bounds for the...

    Using a systematic approach to evaluate Fredholm determinants numerically, we provide convincing evidence that the Airy1-process, arising as a limit law in stochastic surface growth, is not the limit law for the evolution of the largest eigenvalue in GOE matrix diffusion.

    We explore a novel possibility for lowering the solar mixing angle (θ12) from tri-bimaximal mixings, without sacrificing the predictions of maximal atmospheric mixing angle (θ23 = 45°) and zero reactor angle (θ13 = 0°) in the inverted and normal hierarchical neutrino mass models...

    This paper deals with obtaining sufficient conditions for Ψ-asymptotic stability of trivial solution for the linear and nonlinear difference equations on ℕ. And also we provide a way to construct asymptotically stable difference equation from the given equation using Ψ -asymptotic...
