text: গণিতে বহুভাঁজ হল এমন এক টপোলজিকাল স্থান যা স্থানীয়ভাবে প্রতিটি বিন্দুর নিকটে ইউক্লিডীয় স্থানের সমরূপ হবে। আরও সঠিকভাবে বলা যায়, একটি n-মাত্রিক বহুভাঁজের প্রতিটি বিন্দুর একটি সমীপবর্তিতা বিদ্যমান যা n মাত্রার ইউক্লিডীয় স্থানে হোমিওমর্ফিক। আরও নিখুঁত পরিভাষায়, একটি বহুভাঁজ বলতে n-বহুভাঁজকে বোঝানো হয়।
