| Research Abstract |
On caloric morphisms between manifolds, we obtained the following results :
1. The characterization theorem for caloric morphism between semi-riemannian manifolds, as a generalization of the reimannian case.
2. The time variable change and the space dilatation may depend on the space variable for caloric morphisms between semi-riemannian manifolds.
3. The time direction need not be preserved for caloric morphisms between semi-riemannian manifolds.
4. Above 2, 3, and 4 imply that the properties "independence of the time variable change and the space dilatation from the space variable" and "preservation of the time direction" of caloric morphism are the results of the ellipticity of the Laplacian.
5. The equation which characterize the caloric morphism is the same as the heat equation with respect to the weighted tension field.
6. Extension of the Appell transformations to the case of semi-euclidean spaces.
7. The determination of the caloric morphism between semi-euclidean spaces of same dimensions.
8. The determination of the caloric morphism on punctured euclidean space of radial riemannian metric.
9. The determination of the caloric morphism which translates the origin on punctured euclidean space of radial riemannian metric in the case that the dimension is greater than 2.
10. The determination of the caloric morphism on punctured euclidean space of radial semi-riemannian metric.
On the transformation preserving poly-temperatures, we obtained the following results :
The characterization theorem for the transformation preserving poly-temperatures, as a generalization of the caloric merphism. The relation between the transformation preserving poly-temperatures and caloric morphisms.
