Dynamic optimization of a portfolio
Oleg Malafeyev, Achal Awasthi
In this paper, we consider the problem of optimization of a portfolio consisting of securities. An investor with an initial capital, is interested in constructing a portfolio of se…
Distribution of Off-Diagonal Cross Sections in Quantum Chaotic Scattering: Exact Results and Data Comparison
Santosh Kumar, Barbara Dietz, Thomas Guhr +1
The recently derived distributions for the scattering-matrix elements in quantum chaotic systems are not accessible in the majority of experiments, whereas the cross sections are.…
Quantum, noncommutative and MOND corrections to the entropic law of gravitation
Bijan Bagchi, Andreas Fring
Quantum and noncommutative corrections to the Newtonian law of inertia are considered in the general setting of Verlinde's entropic force postulate. We demonstrate that the form fo…
A Survey on Fixed Divisors
Devendra Prasad, Krishnan Rajkumar, A. Satyanarayana Reddy
In this article, we compile the work done by various mathematicians on the topic of the fixed divisor of a polynomial. This article explains most of the results concisely and is in…
How many eigenvalues of a product of truncated orthogonal matrices are real?
P. J. Forrester, J. R. Ipsen, S. Kumar
A truncation of a Haar distributed orthogonal random matrix gives rise to a matrix whose eigenvalues are either real or complex conjugate pairs, and are supported within the closed…
Recursion for the smallest eigenvalue density of -Wishart-Laguerre ensemble
Santosh Kumar
The statistics of the smallest eigenvalue of Wishart-Laguerre ensemble is important from several perspectives. The smallest eigenvalue density is typically expressible in terms of…
