Te-Cheng Liu

Te-Cheng Liu represented Taiwan (TWN) at the 2020 International Mathematical Olympiad, earning a silver medal (rank 121, 26 points). A same-name author appears on a February 2026 arXiv paper on graph outerthickness complexity with Pin-Hsian Lee and Meng-Tsung Tsai at National Taiwan University; the identity link between the olympiad contestant and the researcher is not yet independently confirmed.

• Quant employment verification: UNRESOLVED. No quantitative-finance role or internship (quantitative investment, trading, market-making, hedge fund, systematic/algorithmic trading, or bank/asset-manager/energy/crypto trading) was found for any individual named Te-Cheng Liu. Two distinct same-name candidates surfaced: (1) a computer-science researcher who served as a research assistant in Prof. Meng-Tsung Tsai's group at National Taiwan University, co-authoring the graph-outerthickness paper (ICALP 2026) - an academic research role, not quant; and (2) a Taiwan business professional (Te-Cheng Liu, LINE Taiwan Senior AI Solution Planner, previously Cathay HealthCare Management / Cathay Financial Holdings) - a corporate/AI and business-development role, not quant. No candidate employer operates in quantitative finance; the caller-supplied Cathay lead is a business/AI role and is a different person from the researcher. Verdict is UNRESOLVED rather than NOT CONFIRMED because the identity of any potentially quant-employed Te-Cheng Liu cannot be settled, and no candidate has a supported quant role.
• Represented Taiwan at IMO 2020 as a silver medallist: rank 121, 80.5 percentile, 26 points (P1=7, P2=5, P3=0, P4=7, P5=7, P6=0). Confirms the olympiad identity the brief names.
• Served as a research assistant in Prof. Meng-Tsung Tsai's group at National Taiwan University (through 2026), co-authoring 'Determining the Outerthickness of Graphs Is NP-Hard' (ICALP 2026) - a supported academic role, distinct from the olympiad contestant whose link is only a same-name match.
• Caller-supplied LinkedIn lead https://linkedin.com/in/linus-liu resolves to a different Te-Cheng Liu: a LINE Taiwan senior solution/AI planner with a National Taipei University of Technology architecture master's and National Chengchi University land-economics bachelor's, and prior real-estate/Cathay Insurance roles - inconsistent with a 2020 high-school olympiad contestant.
• A 'Te-Cheng Liu' co-authored the arXiv preprint 'Determining the Outerthickness of Graphs Is NP-Hard' (cs.CC, 7 Feb 2026) with Pin-Hsian Lee and Meng-Tsung Tsai; Tsai's group is at National Taiwan University, so this is a strong education lead but the name match to the IMO contestant is unverified.
• The outerthickness paper also appears in Academia Sinica's Institute of Information Science 2026 publication list, placing the researcher within an Academia Sinica/NTU academic orbit rather than any finance employer.
• Listed as giving the talk 'From Mathematics Competition to Mathematics Research' at an international math-education programme (SIIT/UNIMAS) - a speaking activity, not an employment role; no dates or paid engagement established.
