Algebras of weakly symmetric functions on spaces of Lebesgue measurable functions

Keywords:
symmetric function, weakly symmetric function, analytic function on an infinite dimensional space, space of Lebesgue measurable functionsAbstract
In this work, we investigate algebras of block-symmetric and weakly symmetric polynomials and analytic functions on complex Banach spaces of Lebesgue measurable functions, for which the ppth power of the absolute value is Lebesgue integrable, where p∈[1,+∞),p∈[1,+∞), and Lebesgue measurable essentially bounded functions on [0,1].[0,1]. We construct generating systems of algebras of all weakly symmetric continuous complex-valued polynomials on these spaces. Also we establish conditions under which sets of weakly symmetric analytic functions are algebras.
