order partial derivatives of the Gibbs free energy and to study their continuity. However, the physical meaning of the third- order derivatives is not clear, thus we study the second-order partial derivatives instead. If there were a third-order phase transition, all second-order derivatives woul...
If in a neighbourhood of the point (x 0 , y 0 ) the function f has continuous derivatives up to the order k, then, in some neighbourhood of the point (x 0 , y 0 ), the solution of problem (1.20) has continuous derivatives up to the order (k +1). Let us consider again the ...
On the existence, uniqueness and topological structure of solution sets to a certain fractional differential equation The main goal of this paper is to prove two Aronszajn type theorems for some initial value problems formulated in terms of fractional derivatives. Moreover... D Bugajewska,P Kasprzak...
For a function u(t, x) defined in , we write the partial derivatives as , the spatial gradient as , and the Laplacian of u as . If u is vector-valued, we use to refer to the j-th component of u. We denote by the set of infinitely differentiable functions with compact support in...

We obtain conditions on (R,+) which force that the zero map is the only derivation on a zero-symmetric near-ring R. Throughout the paper we construct several new examples of near-rings which are not rings admitting non-zero derivations, non-zero (σ, σ)
aThe chromatogram of these five derivatives is shown in Fig. 2(b). The RSD of elution times was less than 2.3% for all five monosaccharide derivatives and the LOD was below 0.9 ng. 这五种衍生物色层分离谱显示在。 2 (b)。 洗提时间RSD少于2.3%为所有五种单糖衍生物和LOD在0.9 ng以下是。
