Minimal deformations of the commutative algebra and the linear group   GL(n)
  We consider the relations of generalized commutativity in the algebra of formal series $ M_q (x^i ) $, which conserve a tensor $ I_q $-grading and depend on parameters $ q(i,k) $ . We choose the $ I_q $-preserving version of differential calculus on $ M_q$ . A new construction of the symmetrized tensor product for $ M_q $-type algebras and the corresponding definition of minimally deformed linear group $ QGL(n) $ and Lie algebra $ qgl(n) $ are proposed. We study the connection of $ QGL(n) $ and $ qgl(n) $ with the special matrix algebra $ \mbox{Mat} (n,Q) $ containing matrices with noncommutative elements. A definition of the deformed determinant in the algebra $ \mbox{Mat} (n,Q) $ is given. The exponential parametrization in the algebra $ \mbox{Mat} (n,Q) $ is considered on the basis of Campbell-Hausdorf formula.
