S . A . THE GENERAL SOLUTION OF THE b , PROBLEM FOR GASEOUS NEBULAE
نویسنده
چکیده
The departures of the populations of the excited states of hydrogen from those found under conditions of thermodynamic equilibrium are calculated using a general iterative method. Calculations of b, and d(ln b,,)/dn are carried out for conditions found in gaseous nebulae, and the sensitivity of the solution to certain assumptions is discussed.

$(F,varphi ,alpha )_{s}$-contractions in $b$-metric spaces and applications
In this paper, we introduce more general contractions called $varphi $-fixed point point for $(F,varphi ,alpha )_{s}$ and $(F,varphi ,alpha )_{s}$-weak contractions. We prove the existence and uniqueness of $varphi $-fixed point point for $(F,varphi ,alpha )_{s}$ and $(F,varphi ,alpha)_{s}$-weak contractions in complete $b$-metric spaces. Some examples are supplied to sup...
متن کاملOn Best Proximity Points in metric and Banach spaces
Notice that best proximity point results have been studied to find necessaryconditions such that the minimization problemminx∈A∪Bd(x,Tx)has at least one solution, where T is a cyclic mapping defined on A∪B.A point p ∈ A∪B is a best proximity point for T if and only if thatis a solution of the minimization problem (2.1). Let (A,B) be a nonemptypair in a normed...
متن کاملDetecting the location of the boundary layers in singular perturbation problems with general linear non-local boundary conditions
Singular perturbation problems have been studied by many mathematicians. Since the approximate solutions of these problems are as the sum of internal solution (boundary layer area) and external ones, the formation or non-formation of boundary layers should be specified. This paper, investigates this issue for a singular perturbation problem including a first order differential equation with gen...
متن کاملA Smoothing Technique for the Minimum Norm Solution of Absolute Value Equation
One of the issues that has been considered by the researchers in terms of theory and practice is the problem of finding minimum norm solution. In fact, in general, absolute value equation may have infinitely many solutions. In such cases, the best and most natural choice is the solution with the minimum norm. In this paper, the minimum norm-1 solution of absolute value equation is investigated. ...
متن کاملSolving Fully Fuzzy Dual Matrix System With Optimization Problem
In this paper, the fuzzy dual matrix system as AX + B = CX + D in which A, B, C, D, X are LR fuzzy matrices is studied. At first we solve 1-cut system in order to find the core of LR fuzzy solution; then to obtain the spreads of the LR fuzzy solution, we discuss in several cases. The spreads are obtained by using multiplication, quasi norm and minimization problem with a special objective funct...
