Reducing off-line to on-line: An example and its applications [PDF]
Yugoslav Journal of Operations Research, 2003 We study on-line versions of maximum weighted hereditary subgraph problems for which the instance is revealed in two clusters. We focus on the comparison of these on-line problems with their respective off-line versions.

Mathematics, 2022 The study considers a nonlinear multi-parameter reaction–diffusion system of two Lotka–Volterra-type equations with several delays. It treats both cases of different diffusion coefficients and identical diffusion coefficients.

Lie symmetries and reductions via invariant solutions of general short pulse equation
Frontiers in Physics, 2023 Around 1880, Lie introduced an idea of invariance of the partial differential equation (PDE) under one-parameter Lie group of transformation to find the invariant, similarity, or auto-model solutions.

Consistent Kaluza-Klein Sphere Reductions [PDF]
, 2000 We study the circumstances under which a Kaluza-Klein reduction on an n-sphere, with a massless truncation that includes all the Yang-Mills fields of SO(n+1), can be consistent at the full non-linear level.

Facilitations in Paying Social Security Contributions – Terminological Issues
Prawo Budżetowe Państwa i Samorządu, 2014 The provides an analysis of the term “reductions” in reference to paying contributions. It has been indicated that social insurance debt write offs are not recognized as reductions. Moreover, the author proposes a modification of the term “the mechanisms

BPS states and their reductions [PDF]
, 2012 We develop a method to identify the BPS states in the Hilbert space of a supersymmetric field theory on a generic curved space which preserves at least two real supercharges.

Polytypic Functions Over Nested Datatypes [PDF]
Discrete Mathematics & Theoretical Computer Science, 1999 The theory and practice of polytypic programming is intimately connected with the initial algebra semantics of datatypes. This is both a blessing and a curse. It is a blessing because the underlying theory is beautiful and well developed.

Approximate symmetries of the perturbed KdV-KS equation [PDF]
Iranian Journal of Numerical Analysis and OptimizationThe analysis of approximate symmetries in perturbed nonlinear partial differential equations $(PDEs)$ stands as a cornerstone for unraveling complex physical behaviors and solution patterns.
