Are there any Formal notations commonly used to define the semantics of
a programming language? (Similar to how BNF defines the syntax). I am
exploring semantics and I found various formal notations:


Attribute grammars, Two level (W) Garammar, Denotational Semantics,
Operational semantics, Axiomatic semantics etc.


What I can make out is Attribute grammar is for static semantic checking
and Denotational Semantic, Operational semantics are for dynamic
semantic checking. But in some links I also found that attribute
grammars can be modified to handle dynamic semantics as well. Can anyone
put explain me this. Also though I studied some links related to these,
but I am not very much clear with these. Please tell me some links
which explains these topics in greater detail.
