About estimations of difference for the partial integro-differential equation with small parameter at the leading derivative
I. Kopshaev
This paper is devoted to the study of the singularly perturbed second order partial integro-differential equations. The estimation of the solutions of Cauchy problem is obtained.
About one singularity of the property of disturbed differential systems, that equivalents to linear differential equations
I. Kopshaev
This paper is devoted to the study of the family of morphisms of vector bundle, defined by the systems equivalence to linear differential equations. It is proved, that the specifie…
