If I am not sure which module the function I want belongs to, I can directly enter a keyword in the search bar to search (I am very thankful that my mathematica is in Chinese). The effect is as follows: A little surprise: when I select "Symbol and Numerical Calculation" in the secon...

When you don’t specify precision, Mathematica uses MachinePrecision, which is a built-in symbol that denotes the precision native to your computer’s floating-point capabilities. The numerical value of MachinePrecision is stored in a variable $MachinePrecision. In[31]:= $MachinePrecision Out[31...
By an abuse of notation we will use the same symbol L for the contact line bundle and the corresponding Weil divisor. On Xsm we have an equality of classes of Weil divisors (n+1)L|Xsm=−KXsm given by ϑ∧(dϑ)∧n. By the normality of X we can prolong this equality to whole...
