Influence of the Luminance and Opponent Chromatic Channels on Stereopsis with Randomdot Stereograms

The present work examines the relationship between random-dot stereograms (via the disparity range parameter) and color-vision mechanisms (via the luminance channel and red-green and tritan directions at isoluminance). The results clearly indicate that the variations in the stereograms along red-green confusion lines contribute to stereopsis. Stereoscopic perception depends on spatial informati...

Normal Ideals of Graded Rings

For a graded domain R = k[X0, ...,Xm]/J over an arbitrary domain k, it is shown that the ideal generated by elements of degree ≥ mA, where A is the least common multiple of the weights of the Xi, is a normal ideal.

General canonical models for graded normal logics (graded modalities IV)

We prove the canonical models introduced in [D] do not exist for some graded normal logics with symmetric models, namely KB ~ KBD ~ KBT ~ so that we define a new kind of canonical models, the general ones, and show they exist and work well in every case.

Decidability by Filtrations for graded normal logics (graded modalities V)

1. I n t r o d u c t i o n Graded normal logics ( G N L s ) are the extensions of modal normal logics to a language with graded modalities. The interpretation in usual Kripke models of a formula <>hA (n < w), whose main operator is a graded possibility, is there are more than n accessible worlds where A is true. When graded modalities were introduced (in [7], independently rediscovering a forme...
