What Do H and * Symbols Mean in Epp's Discrete Math Textbook?

[logan3]

Maybe it's explained somewhere in her book, but what do the Hs and *s mean beside some of the problems in Epp's Discrete Math, 4E textbook?

Are there any other notations I should make note of in the book as well?

Thank-you for your help.

I guess you should provide some context behind the usage of the notations. Because there might not be a standard notation for what the author wants to discuss, or the author very well could be using a non-standard notation.

The context is stated in the opening post.

you don't understand what context means ... in what specific concept/topic is this notation used ?

can you cite a specific chapter, preferably with a page number(s)?

I do understand what context means. However, you don't understand how to be polite. So I won't further respond to your posts.

I emailed the author. She said that the meaning of these two symbols were placed only under the first Exercise Set of each Chapter, rather than in the Preface. "Appendix B contains either full or partial solutions to all exercises with blue numbers. When the solution is not complete, the exercise number has an H next to it. A ✶ next to an exercise number signals that the exercise is more challenging than usual."

It seems the problem is solved. I thought that the symbol $H$ was some mathematical operator. But instead it's just a label attached to some of the exercises.
