The first expression after looking it up states that the this is the partial derivative of a wave function with respect to t, holding the x constant. Hence, I presume that he subscript here means that variable is held constant.Nugatory said:You will get better answers of you can tell us more about exactly where you found these expressions and how they're being used. I and many other people here could make some good guesses, but these subscripts are often used with meanings that are only clear in context... So we need that context to give you more than guesses.

A subscript is a small character, number, or symbol written below the line of text. It is used in mathematical and scientific notation to indicate a specific quantity or property.
A subscript is written below the line of text, while a superscript is written above the line of text. Subscripts are commonly used in chemical formulas and mathematical equations, while superscripts are often used for exponents or footnotes.
In a chemical formula, a subscript signifies the number of atoms of a specific element present in a molecule. For example, the subscript of 2 in H2O indicates that there are 2 hydrogen atoms present in a water molecule.
Subscripts are used in mathematical equations to provide additional information and clarify the meaning of the equation. They can represent variables, coefficients, and other important quantities in the equation.
The specific method for formatting subscripts may vary depending on the software you are using. In general, you can use the "subscript" formatting option to apply a subscript to a character or select the character and use the shortcut keys (Ctrl + = on a PC or Command + = on a Mac).
