Inverse optimisation and linear programming have emerged as crucial instruments in addressing complex decision-making problems where underlying models must be inferred from observed behaviour. At its ...

The problem of controlled linear calibration with a multivariate response and univariate explanatory variable is considered. Exact expressions (in terms of functions ...

The paper defines and studies the Drazin inverse for a closed linear operator A in a Banach space X in the case that 0 is an isolated spectral point of A. Results include an integral representation ...
