Computation of the Expected Euler Characteristic for the Largest Eigenvalue of a Real Non-central Wishart Matrix
Nobuki Takayama, Lin Jiu, Satoshi Kuriki +1
We give an approximate formula for the distribution of the largest eigenvalue of real Wishart matrices by the expected Euler characteristic method for the general dimension. The fo…

Rational Solutions of First-Order Algebraic Ordinary Difference Equations
Thieu N. Vo, Yi Zhang
We propose an algebraic geometric approach for studying rational solutions of first-order algebraic ordinary difference equations. For an autonomous first-order algebraic ordinary…

Apparent Singularities of D-finite Systems
Shaoshi Chen, Manuel Kauers, Ziming Li +1
We generalize the notions of singularities and ordinary points from linear ordinary differential equations to D-finite systems. Ordinary points of a D-finite system are characteriz…
