Fictitious domain method and separated representations for the solution of boundary value problems on uncertain parameterized domains

► We propose a tensor-based method for the solution of PDEs defined on uncertain parameterized domains. ► We use a fictitious domain approach to obtain a formulation in a tensor product space. ► We use a PGD algorithm for the construction of a tensor approximation of the solution. ► We introduce a c...
