Program slicing is a technique that extracts, given a program and a criterion that is one or several instructions in this program, a simpler program, called a slice, that has the same behavior as the initial program with respect to the criterion. Program analysis techniques focus on establishing the properties of a program. These techniques are costly, and their complexity increases with the size of the program. Therefore, it would be interesting to apply these techniques on slices rather than the initial program, but it requires theoretical foundations to interpret the results obtained on the slices. This thesis provides this justification for runtime error detection. In this context, two questions arise. If an error is detected in the sli...
