Second Noether’s theorem with time delay

In this paper, we consider variational problems with delayed argument. Simple proofs of the first and second Noether theorems are given. Applying our results to some concrete problems we obtain conservation laws for systems with delay.     

Noether’s theorem for fractional variational problems of variable order

We prove a necessary optimality condition of Euler-Lagrange type for fractional variational problems with derivatives of incommensurate variable order. This allows us to state a version of Noether’s theorem without transformation of the independent (time) variable. Considered derivatives of variable order are defined in the sense of Caputo.     

Determination of gaseous products of thermal degradation of thiram

Journal of Thermal Analysis and Calorimetry - Thiram is one of the commonly used carbamate pesticides. Unfortunately, the thermal degradation and combustion of that substance can lead to emission...
