Abstract: Trade friction refers to the conflicts and disputes in various fields such as trade and economic policies between trading nations in order to safeguard their political and economic interests ...

We study the basic quantum mechanics for a fully general set of Dirac matrices in a curved spacetime by extending Pauli's method. We further extend this study to three versions of the Dirac equation: ...

👉 Learn how to solve exponential equations with the same base. An exponential equation is an equation in which a variable occurs as an exponent. To solve an exponential equation, we make the base of ...
