Logical Operations and Invariance
I present a notion of invariance under arbitrary surjective mappings for operators on a relational finite type hierarchy generalizing the so called Tarski-Sher criterion for logicality and I characterize the invariant operators as definable in a fragment of the first-order language. These results are compared with those obtained by Feferman and it is argued that further clarification of the not...
متن کاملLogical operations and Kolmogorov complexity
Conditional Kolmogorov complexity can be understood as the complexity of the problem “ ”, where is the problem “construct ” and is the problem “construct ”. Other logical operations ( ) can be interpreted in a similar way, extending Kolmogorov interpretation of intuitionistic logic and Kleene realizability. This leads to interesting problems in algorithmic information theory. Some of these ques...
متن کاملLogical operations with Localized Structures
We show how to use excitable regimes mediated by localized structures (LSs) to perform AND, OR and NOT logical operations providing full logical functionality. Our scheme is general and can be implemented in any physical system displaying LSs. In particular, LSs in nonlinear photonic devices can be used for all-optical computing applications where several reconfigurable logic gates can be imple...
متن کاملLogical theories and compatible operations
We survey operations on (possibly in nite) relational structures that are compatible with logical theories in the sense that, if we apply the operation to given structures then we can compute the theory of the resulting structure from the theories of the arguments (the logics under consideration for the result and the arguments might di er). Besides general compatibility results for these opera...
متن کاملMulti-level threshold based edge detector using logical operations
Edge detection is a very significant feature of image processing and refers to the algorithms, which are intended for identifying points in a digital image where the image intensity changes significantly. The need of edge detection is to find the discontinuities in intensity, surface direction, change in texture properties, and variation in scene illumination. This paper proposes a rapid and su...
