#### Multiple solutions for the dirichlet second-order boundary value problem of nonsingular type

(Elsevier BV, 1999-04-01)

#### Boundary value problems of nonsingular type on the semi-infinite interval

(Mathematical Institute, Tohoku University, 1999-01-01)

Existence of a positive solution is established for second order boundary value problems on the semi-infinite interval.

#### Multiple solutions for higher-order difference equations

(Elsevier BV, 1999-05-01)

#### Existence of solutions to singular integral equations

(Elsevier BV, 1999-05-01)

#### Singular discrete boundary value problems

(Elsevier BV, 1999-05-01)

#### Continuation methods for closed, weakly closed, dkt, and wdkt maps

(Elsevier BV, 1999-10-01)

#### Acquisition and analysis of adaptive optics imaging polarimetry data

(EDP Sciences, 1999-07-01)

The process of data taking. reduction and calibration of near-infrared imaging polarimetry data taken with the ESO Adaptive Optics System ADONIS is described. The ADONIS polarimetric facility is provided by a rotating wire ...

#### Limits to quantum gravity effects on energy dependence of the speed of light from observations of tev flares in active galaxies

(American Physical Society (APS), 1999-09-13)

We have used data from a TeV gamma-ray flare associated with the active galaxy Markarian 421 to place bounds on the possible energy dependence of the speed of light in the context of an effective quantum gravitational ...

#### Kinematic interpretation of the centaurus a absorption‐line system

(IOP Publishing, 1999-05-10)

The location of the gas responsible for the absorption-line system toward the nucleus of Centaurus A is a puzzle. It is generally accepted that the line features close to the systemic velocity originate in the disk. The ...

#### A bound on the schur multiplier of a prime-power group

(Cambridge University Press (CUP), 1999-10-01)

The paper improves on an upper bound for the order of the Schur multiplier of a finite p-group given by Wiegold in 1969. The new bound is applied to the problem of classifying p-groups according to the size of their Schur ...
