Sun made the following further conjecture (which is the linear extension of the Erds-Heilbronn conjecture): For any finite subset A of a field F and nonzero elements a1,., an of F, we have |{a1x1 + ··· + anxn: x1,., xn ∈ A, and xi = xj if i = j}| min {p(F) δ...
Temporal dissipative solitons in a continuous-wave laser-driven nonlinear optical microresonator were observed. The solitons were generated spontaneously when the laser frequency was tuned through the effective zero detuning point of a high-resonance, which led to an effective red-detuned pumping. Transit...
