Constrained spectral clustering via multi–layer graph embeddings on a grassmann manifold
International Journal of Applied Mathematics and Computer Science, 2019 We present two algorithms in which constrained spectral clustering is implemented as unconstrained spectral clustering on a multi-layer graph where constraints are represented as graph layers.

Janossy densities for chiral random matrix ensembles and their applications to two-color QCD
Journal of High Energy Physics, 2019 We compute individual distributions of low-lying eigenvalues of massive chiral random matrix ensembles by the Nyström-type quadrature method for evaluating the Fredholm determinant and Pfaffian that represent the analytic continuation of the Janossy ...

A Note on the Construction of Explicit Symplectic Integrators for Schwarzschild Spacetimes
The Astrophysical Journal, 2022 In recent publications, the construction of explicit symplectic integrators for Schwarzschild- and Kerr-type spacetimes is based on splitting and composition methods for numerical integrations of Hamiltonians or time-transformed Hamiltonians associated ...

Third-order explicit two-step Runge-Kutta-Nyström method for solving second-order ordinary differential equations [PDF]
, 2012 A two-stage explicit two-step Runge-Kutta-Nyström (TSRKN) method is constructed for the numerical integration of special second-order IVPs. Algebraic order conditions of the method are obtained and third-order method is derived.

Stability of the Nyström Method for the Sherman–Lauricella Equation [PDF]
, 2011 The stability of the Nyström method for the Sherman–Lauricella equation on piecewise smooth closed simple contour $\Gamma$ is studied. It is shown that in the space $L_2$ the method is stable if and only if certain operators associated with the corner ...
