Basis properties of eigenfunctions of a generalized gasdynamic Frankl problem
The paper deals with two generalized gasdynamic Frankl problems. The theorems give formulas for eigenvalues and eigenfunctions. The authors describe the completeness of eigenfunctions in proper spaces of square integrable functions and study cases when the eigenfunctions form a Riesz basis.
