Approximation of the pth Roots of a Matrix by Using Trapezoid Rule
International Journal of Mathematics and Mathematical Sciences, 2012 The computation of the roots of positive definite matrices arises in nuclear magnetic resonance, control theory, lattice quantum chromo-dynamics (QCD), and several other areas of applications.

Mathematics, 2020 The derivation of integrals in the table of Gradshteyn and Ryzhik in terms of closed form solutions is always of interest. We evaluate several of these definite integrals of the form ∫ 0 ∞ log ( 1 ± e − α y ) R ( k , a , y ) d y in ...

Non-positivity of the Wigner function and bounds on associated integrals
, 2003 The Wigner function shares several properties with classical distribution functions on phase space, but is not positive-definite. The integral of the Wigner function over a given region of phase space can therefore lie outside the interval [0,1].

Integration on quantum Euclidean space and sphere in $N$ dimensions
, 1995 Invariant integrals of functions and forms over $q$ - deformed Euclidean space and spheres in $N$ dimensions are defined and shown to be positive definite, compatible with the star - structure and to satisfy a cyclic property involving the $D$ - matrix ...

Algebraic {$q$}-Integration and Fourier Theory on Quantum and Braided Spaces
, 1994 We introduce an algebraic theory of integration on quantum planes and other braided spaces. In the one dimensional case we obtain a novel picture of the Jackson $q$-integral as indefinite integration on the braided group of functions in one variable $x$.
