We introduce a bounce qq-hit number which is a refined notion of a qq-hit number. We characterize coefficients of enβˆ’1,1e_{n-1,1} of chromatic quasisymmetric functions for the class of unit interval graphs on the elementary basis and show that it is positive. This is partial proof of the Stanley-Stembridge conjecture on chromatic quasisymmetric functions.보완 κ·Έλž˜ν”„κ°€ μ΄λΆ„λ˜λŠ” λ‹¨μœ„ 간격 κ·Έλž˜ν”„λ“€μ— λŒ€ν•˜μ—¬ 채색 μ€€λŒ€μΉ­ ν•¨μˆ˜μ˜ κΈ°λ³Έ 기저에 λŒ€ν•œ κ³„μˆ˜λ₯Ό μƒκ°ν•΄λ³΄μž. κ³„μˆ˜λ“€μ„ νŠΉμ • qq-hit numberλ“€λ‘œ ν‘œν˜„ν•  수 μžˆλ‹€λŠ” 사싀이 μ•Œλ €μ Έ μžˆλ‹€. μš°λ¦¬λŠ” qq-hit numberλ₯Ό κ°œμ„ ν•œ bounce qq-hit numberλ₯Ό μ •μ˜ν•˜κ³ , μž„μ˜μ˜ λ‹¨μœ„ 간격 κ·Έλž˜ν”„λ“€μ— λŒ€ν•˜μ—¬ 채색 μ€€λŒ€μΉ­ ν•¨μˆ˜μ˜ enβˆ’1,1e_{n-1,1}의 κ³„μˆ˜λ₯Ό μ΄λ‘œμ„œ ν‘œν˜„ν–ˆλ‹€. enβˆ’1,1e_{n-1,1}의 κ³„μˆ˜κ°€ μ–‘λΆ€ν˜Έκ°€ λœλ‹€λŠ” 것 λ˜ν•œ λ³΄μ˜€λŠ”λ°, μ΄λŠ” 채색 μ€€λŒ€μΉ­ ν•¨μˆ˜μ— λŒ€ν•œ Stanley-Stembridge κ°€μ„€μ˜ 뢀뢄적인 증λͺ…이닀.Abstract 1.Introduction 1 2.
