General covariant derivatives for general connections
In this paper we introduce the general covariant derivatives of vertical-valued tensor fields with respect to a general connection on a fibered manifold and a classical connection on the base. We prove that the general<...

Transformation of spatial and perturbation derivatives of travel time at a general interface between two general media
We consider the partial derivatives of travel time with respect to both spatial coordinates and perturbation parameters. We derive the explicit equations for transforming these travel-time derivatives of arbitrary orders at...

Generalized directional derivatives
The book is devoted to generalized second-order directioanal derivatives and to the class of functions for which the lower Dini derivative is Lipschitz. The optimality conditions for the problems without constraints were st...

Convexity and generalized second-order derivatives for locally lipschitz functions
We define the generalized second-order directional derivatives by means of the Clarke generalized gradient for locally Lipschitz functions. Then we give characterization of convexity and state a new sufficient optimality co...

Combined Leftmost Derivations in Matrix Grammars
It is an open problem, whether matrix grammars with erasing productions using leftmost derivation of type three generate the whole family of recursively using leftmost derivation of type one and all other matrices usin...

Reduction theorem for general connections
We prove the (first) reduction theorem for general and classical connections, i.e. we prove that any natural operator of a general connection on a fibered manifold and a classical connection on the base manifold can be expressed as ...

Explicit formulas for generators of triangular norms
The paper shows a direct correspondence between the first partial derivatives of a continuous Archimedean triangular norm and the first derivatives of its additive generator. An explicit formula for the additive generat...

Homotopy derivations
by adding a generator with "derivation relations". For a wide class of Koszul operads , in particular and , we describe the strong homotopy derivations by coderivations and show. We give examples of strong homotopy der...

On Lipschitz behaviour of some generalized derivatives
The aim of present paper is to compare various forms of stable property at some point. By stable property we mean the Lipschitz property of some generalized derivatives related only to the reference point. Namely we compare Lipschit...

Derived, coderived, and contraderived categories of locally presentable abelian categories
