Contamination-Free Measures and Algebraic Operations
  An open concept of rough evolution and an axiomatic approach to granules was
also developed recently by the present author. Subsequently the concepts were
used in the formal framework of rough Y-systems (RYS) for developing on
granular correspondences by her. These have since been used for a new approach
towards comparison of rough algebraic semantics across different semantic
domains by way of correspondences that preserve rough evolution and try to
avoid contamination. In this research paper, new methods are proposed and a
semantics for handling possibly contaminated operations and structured bigness
is developed. These would also be of natural interest for relative consistency
of one collection of knowledge relative other.
