Foundations of Discrete Mathematics
K. D. Joshi
Discrete mathematics is “the study of mathematical structures that are fundamentally discrete in the sense of not supporting or requiring the notion of continuity.” This is the context in which one should read Joshi's dedication:
“To my discreet wife Swarada, for her continuous support.”
