 Neolithic age indicates that the spread of agriculture involved nomadic fo
 raging as a gradual transition across regions. The spreading velocity of a
 griculture is roughly constant\, according to archaeological evidence of t
 he Neolithic transition. Many theoretical attempts have been made to under
 stand such a phenomenon through mathematical modeling. Existing models of 
 the spread of agriculture indicate that expansion velocity is faster than 
 the observed rate. To understand this difference\, we propose a three-comp
 onent reaction-diffusion/ODE system involving two types of farmers: seden
 tary and migratory. Moreover\, we introduce the influence of farming techn
 ology on the spread of agriculture in the Neolithic age. We aim to study t
 he relationship between the expanding velocity and farming technology.</p>
  <p>In this talk\, we focus on the one-dimensional traveling wave solution
 s with minimal velocity when the expanding pattern of farmers is radially 
 symmetric. Finally\, our model suggests that the minimal velocity of trave
 ling waves explains the spreading velocity of agriculture when the expandi
 ng pattern exhibits radial symmetry. Numerical simulations reveal that the
  minimal velocity of traveling wave solutions decreases as farming technol
 ogy advances. Furthermore\, we investigate the planar stability of the min
 imal traveling waves and subsequently the occurrence of two-dimensional tr
 aveling wave solutions in the context of the development of farming techno
 logy. </p> <p>M. Humayun Kabir earned his Ph.D. in Mathematical Sciences 
 from Meiji University\, Japan\, under the supervision of Prof. Masayasu Mi
 mura. He has been a Visiting Research Fellow at the Center for Mathematica
 l Modeling &amp\; Applications at Meiji University since April 2018. Humay
 un leads the Mathematical and Computational Biology Research Group at the 
 Department of Mathematics\, Jahangirnagar University\, Bangladesh. His res
 earch interests include a mathematical model-aided understanding of biolog
 ical phenomena\, particularly mathematical ecology\, population dynamics\,
  reaction-diffusion equations\, and pattern formation. Currently\, Dr. Kab
 ir is serving as the secretary of the Bangladesh Mathematical Society and 
 the Bangladesh Society for Mathematical Biology. </p> <p><strong>ONLINE B
