The academicians and corresponding members of the Bulgarian Academy of Sciences form their assemblies and branches, according to Art. 7 of the Statute of the Bulgarian Academy of Sciences.
The academicians and corresponding members form two assemblies: the Assembly of Academicians (AA) and the Assembly of Academicians and Corresponding Members (AACM). The Chairman of both assemblies is the President of BAS.
AACM establishes branches by groups of scientific and creative divisions which unite all members of the respective division. The established branches are approved by the Governing Council of BAS and are called “Branches of the Bulgarian Academy of Sciences”.
