solving the Three-Neutrino Prob.em as One of the Three-b.dy Prob.ems in Physics

b. using the stand.rd PMNs (Pontecorvo-Maki-Nakagawa-sakata) mixing matrix and.applying the rule for the sum of the oscillation prob.b.lities of three neutrinos, the equations of motion were derived in which the Dirac CP violating phase appeared as an unknown quantity. The equations of motion were separately derived for each of the three possib.e transitions for flavor-neutrino oscillations. Two roots of those equations were ob.ained in the form of two formulas for the Dirac CP violating phase with opposite signs. In the mathematical sense, the connection b.tween those formulas was estab.ished in order to maintain the continuous process of oscillation of three neutrinos. This made it possib.e to calculate the numerical value for the Dirac CP violating phase, the Jarlskog invariant and.to write the general form of the PMNs mixing matrix in the final form in which all its elements are defined with explicit numerical values.

On the Numb.r of Primes in the Interval (x, 2x) b. an Elementary Method

引用

Advances in Pure Mathematics 2024年第1期14卷 16-29页

作者： sudhindra b. Kittur Independent Researcher Mumbai India

An elementary formula to know the numb.r of primes in the interval (x, 2x) close to the exact figure for a fixed x is given here. A new elementary equation is derived (a relation b.tween prime numb.rs and.composite numb.rs distrib.ted in the interval [1, 2x]). An elementary method to know the numb.r of primes in a given magnitude is suitab.y placed in the form of a general formula, and.we have proved it. The general formula is applied to the terms of the equation, and.a tactical simplification of the terms gives rise to an expression whose verification envisages scope for its further studies.
