How to play a disc brake [PDF]
, 1999 We consider a gyroscopic system under the action of small dissipative and non-conservative positional forces, which has its origin in the models of rotating bodies of revolution being in frictional contact.

Pauli-Villars regularization and discrete light-cone quantization in Yukawa theory [PDF]
, 1999 The techniques of Pauli-Villars regularization and discrete light-cone quantization are combined to analyze Yukawa theory in a single-fermion truncation.

Electronic Journal of Qualitative Theory of Differential EquationsWe prove the existence of at least one positive periodic solution for a second-order damped nonlinear differential equation with an indefinite singularity by assuming the corresponding linear equation have a positive Green's function.

Discrete dynamical systems associated with root systems of indefinite type
, 2001 A geometric charactrization of the equation found by Hietarinta and Viallet, which satisfies the singularity confinement criterion but which exhibits chaotic behavior, is presented.

Singular maps on exotic 4-manifold pairs [PDF]
, 2013 We show examples of pairs of smooth, compact, homeomorphic 4-manifolds, whose diffeomorphism types are distinguished by the topology of the singular sets of smooth stable maps defined on them.

Geometric Engineering of N=2 CFT_{4}s based on Indefinite Singularities: Hyperbolic Case
, 2003 Using Katz, Klemm and Vafa geometric engineering method of $\mathcal{N}=2$ supersymmetric QFT$_{4}$s and results on the classification of generalized Cartan matrices of Kac-Moody (KM) algebras, we study the un-explored class of $\mathcal{N}=2$ CFT$_{4}$s

On the Generic Use of Indefinite Singulars [PDF]
Journal of Semantics, 2001 The distribution of indefinite singular generics is much more restricted than that of bare plural generics. The former, unlike the latter, seem to require that the property predicated of their subject be, in some sense, definitional'. Moreover, the two constructions exhibit different scopal behaviour, and differ in their felicity in conjunctions ...

Indefinite Morse 2-functions; broken fibrations and generalizations
, 2014 A Morse 2-function is a generic smooth map from a smooth manifold to a surface. In the absence of definite folds (in which case we say that the Morse 2-function is indefinite), these are natural generalizations of broken (Lefschetz) fibrations.

Quantum Black Holes from Quantum Collapse [PDF]
, 2001 The Schwarzschild black hole can be viewed as the special case of the marginally bound Lema\^\i tre-Tolman-Bondi models of dust collapse which corresponds to a constant mass function.

Broken Lefschetz fibrations and smooth structures on 4–manifolds
, 2012 The broken genera are orientation preserving diffeomorphism invariants of closed oriented 4-manifolds, defined via broken Lefschetz fibrations. We study the properties of the broken genera invariants, and calculate them for various 4-manifolds, while ...
