Title: | On the behaviour of Colombeau's generalized functions at a point: Applications to semilinear systems | Authors: | Pilipović, Stevan Stojanović M. |
Issue Date: | 1-Jan-1997 | Journal: | Publicationes Mathematicae | Abstract: | Abstract. We define the quasiasymptotics at zero (or at any other point) of a Colombeau's generalized function, element of script G sign, and show that this definition restrected on a Schwartz's distribution embedded into script G sign gives the well-known notion of the quasiasymptotics at zero and, in a special case, the value at zero. We analyze the quasiasymptotics of a Cauchy problem for a strictly semilinear hyperbolic system and show that under suitable assumptions on the non-linear term, the behaviour of the solution is determined by the behaviour of initial data. | URI: | https://open.uns.ac.rs/handle/123456789/13354 | ISSN: | 00333883 |
