My policy is to ensure that the mathematical texts on this site are readable with any browser. The following substitutes will be used for unavailable symbols:
x multiplication sign blng 'belong(s) to' ^ superscripts (such as powers) iff 'if and only if' (as usual) =/= not equal incls 'includes' (set inclusion) <= less than or equals log logarithm to the base 2 o small circle; subscript zero not blng 'do(es) not belong to' --> tends to sqrt square root ==> implies Sum summation (capital sigma) <--> one-to-one correspondence union set union Ao Aleph-zero oo symbol for infinity a1 a subscript 1
Happily, some mathematical articles and those on theoretical physics are now in PDF format, but some are still only in HTML format.
