May 19	accepted	properties of recursively enumerable sets
May 18	comment	properties of recursively enumerable sets Thank you, could you define the numeral for number x?

May 18	comment	Recursive function with code $n$, whose output is the number $n$ itself Thank you for the hint @tci.

May 17	comment	Decidability and undecidability of a set or language I don't understand very well, how the set you defined is equal to the set $A$ in my question?
May 17	comment	Decidability and undecidability of a set or language Thank you. So you're saying that they're not decidable?
May 17	asked	Recursive function with code $n$, whose output is the number $n$ itself
May 17	comment	decidability of $\{x\|W_x \text{is different from K in only finitely many elements}\}$ I asked another question about two decidable sets, I'd be grateful if you could provide a detailed argument for them as well. In case you want to, of course. Thanks anyway.

May 17	accepted	Is the difference of two recursively enumerable sets, reducible to $K$?

May 17	accepted	decidability of $\{x\|W_x \text{is different from K in only finitely many elements}\}$
May 16	comment	Is $\{(x, y) \mid y \in \text{Range}(\phi_x)\}$ decidable? Very well explained, thank you.
May 16	accepted	Is this language decidable?
