▁important ▁role ▁in ▁understanding ▁function ▁behavior . ▁Ex amples ▁of ▁classes ▁of ▁functions ▁with ▁a ▁rich ▁structure ▁are , ▁in ▁addition ▁to ▁the ▁convex ▁functions , ▁the ▁sub harm onic ▁functions ▁and ▁the ▁pl ur is ub harm onic ▁functions . ▁Ge omet r ically , ▁these ▁classes ▁of ▁functions ▁correspond ▁to ▁convex ▁domains ▁and ▁pseudo con vex ▁domains , ▁but ▁there ▁are ▁also ▁other ▁types ▁of ▁domains , ▁for ▁instance ▁line ally ▁convex ▁domains ▁which ▁can ▁be ▁generalized ▁using ▁convex ▁analysis . ▁A ▁great ▁deal ▁is ▁already ▁known ▁about ▁these ▁domains , ▁but ▁there ▁remain ▁some ▁fasc in ating , ▁un sol ved ▁problems . ▁This ▁theme ▁is ▁mainly ▁theoretical , ▁but ▁there ▁are ▁computational ▁aspects ▁of ▁the ▁domains ▁studied , ▁and ▁these ▁computational ▁aspects ▁are ▁certainly ▁worthy ▁of ▁further ▁study . ▁ ▁References ▁ ▁Category : Comple x ▁analysis ▁Category : Con vex ▁analysis <0x0A> </s> ▁Ham pt ons ▁is ▁a ▁magazine ▁founded ▁in ▁ 1 9 7 8 ▁and ▁published ▁th ir teen ▁times ▁throughout ▁the ▁year ▁focused ▁on ▁real ▁estate , ▁interior ▁design , ▁fashion , ▁art , ▁culture , ▁d ining , ▁entertain ment , ▁fit ness , ▁and ▁phil anth ropy . ▁The ▁magazine ▁was ▁published ▁by ▁N iche ▁Media , ▁which ▁was ▁founded ▁in ▁ 1 9 9 8 ▁by ▁Jason ▁B inn , ▁and ▁has ▁an ▁approximate ▁circul ation ▁of ▁ 4 0 , 0 0 0 ▁– ▁ 5 0 , 0 0 0 ▁copies , ▁distributed ▁all ▁over ▁The ▁Ham pt ons .
