The optimal control problem for the nonlinear elliptic equation is considered. The corresponding control-state mapping is not Gataux differentiable. Necessary conditions of optimality are obtained by means of the extended derivatives theory.

We study particle production of coherently oscillating inflaton in the semiclassical theory of gravity by representing inflaton in coherent and squeezed state formalisms. A comparative study of the inflaton in classical gravity with coherent state inflaton in semiclassical gravity is also presented. email: [email protected] ∗Corresponding address : P.K.Suresh, School of Physics,University of...

This paper discusses the definition of the state space and corresponding choice sets that figure in the theory of decision making under uncertainty. It elucidates an approach that overcomes some conceptual difficulties with the standard models and accommodates a procedure for expanding the state space in the wake of growing awareness.

after the iranian mashrooté revolution, the shiite political thought faced a new era of much attention, contemplation and explanation, when religious scholars embarked on a new research project to address the new situation. the most serious attempt to deal with the theoretical gap and crisis in islamic state was contributed by imam khomaini. in his theory of state, he conjoined the shiite princ...

Analyses and investigations on river flow behavior are major issues in design, operation and studies related to water engineering. Thus, recently the application of chaos theory and new techniques, such as chaos theory, has been considered in hydrology and water resources due to relevant innovations and ability. This paper compares the performance of chaos theory with Anfis model and discusses ...

the problem of pole assignment, also known as an eigenvalue assignment, in linear discrete-time periodic systems in discs was solved by a novel method which employs elementary similarity operations. the former methods tried to assign the points inside the unit circle while preserving the stability of the discrete time periodic system. nevertheless, now we can obtain the location of eigenvalues ...

we have investigated structure and electronic properties of au and si liner chains using the firstprinciplesplane wave pseudopotential method. the transport properties and conductance of these twoliner chains are studied using landauer approaches based on density functional theory (dft). weobtain density of states and band gap using kohn-sham and wannier functions as well as quantumconductivity...

We present a way to construct a pilot-wave model for quantum field theory. The idea is to introduce beables corresponding only to the bosonic degrees of freedom and not to the fermionic degrees of freedom of the quantum state. We illustrate this idea for quantum elec-trodynamics. The beables will be field beables corresponding to the electromagnetic field and they will be introduced in a simila...
