Resonances in a spring-pendulum: algorithms for equivariant singularity theory [PDF]

open access: yes, 1998
A spring-pendulum in resonance is a time-independent Hamiltonian model system for formal reduction to one degree of freedom, where some symmetry (reversibility) is maintained.

Mathematical Singularities in the Farthest Confines of the Universe—And a Brief Report on Its Evolutionary History

open access: yesUniverse, 2023
It is advisable to avoid and, even better, demystify such grandiose terms as “infinity” or “singularity” in the description of the cosmos. Its proliferation does not positively contribute to the understanding of key concepts that are essential for an ...

Singularity, Wielandt’s lemma and singular values

open access: yesJournal of Computational and Applied Mathematics, 2010
The authors obtain some upper and lower bounds for the largest and the smallest singular values of certain complex matrices based on the entries and diagonal dominance. A relationship between largest singular value of a block matrix and its block norm matrix is obtained. Numerical examples are given to demonstrate the usefulness of their results.

ON RESOLVING SINGULARITIES [PDF]

open access: yesJournal of the London Mathematical Society, 2001
Let V be an irreducible affine algebraic variety over a field k of characteristic zero, and let (f_0,...,f_m) be a sequence of elements of the coordinate ring. There is probably no elementary condition on the f_i and their derivatives which determines whether the blowup of V along (f_0,...,f_m) is nonsingular. The result is that there indeed is such an

hpcng/singularity: Singularity 3.6.1

open access: yes, 2020
Singularity 3.6.1 is a patch release fixing some bugs raised soon after the 3.6.0 release. In particular, an issue where supplying an empty string "" as the destination to singularity build could result in the removal of the current directory has been ...

On Security Singularities [PDF]

open access: yesProceedings of the New Security Paradigms Workshop, 2018
In future studies involving artificial intelligence, the so-called technological singularity is a key theme. It refers to a hypothetical point in the future where technological progress becomes automated through the creation of a new form of intelligence.
