Asymptotically quasi-homogeneous generalized functions at the origine

Generalized functions having quasiasymptotics along special groups of transformations of independent variables in the asymptotic scale of regularly varying functions are said to be asymptotically homogeneous along these transformations groups. In particular, all “quasihomogeneous” distributions have this property. A complete description of asymptotically homogeneous in the origin distributions along a transformation group determined by a vector $a\in\mathbb R_+^n$ is obtained (including the case of critical orders). Special distribution spaces are introduced and investigated to this end. The results obtained in the paper are applied for construction of asymptotically quasihomogeneous solutions of differential equations whose symbols are quasihomogeneous polynomials.
